How do I register on MEXC with only $100 and get the best welcome bonus?

Go to mexc.com, click 'Sign Up', enter your email and a strong password, then — this is the important part — enter the Beginner Commission-Free Welcome Code **Oy8BzEhmaK** in the referral/invite code field. This unlocks 0% maker fees on spot trading and access to exclusive beginner bonuses not available to standard sign-ups. After verifying your email and completing basic KYC, you can deposit as little as $1 USDT and start trading immediately. The whole process takes under 10 minutes.

Which crypto exchange is best for beginners with a small budget in 2026?

For small budgets under $100, MEXC stands out because it offers 0% maker fees on spot trading, no minimum deposit requirement, and supports over 2,300 trading pairs. This means more of your $100 actually works for you rather than getting eaten by fees. Binance and OKX are also solid options but have slightly higher fee structures for small-volume traders. If you're just starting out, MEXC's fee-free model is hard to beat.

Is MEXC safe for beginners with small deposits?

Yes. MEXC has been operating since 2018, serves over 10 million users across 200+ countries, and holds regulatory licenses in multiple jurisdictions. The platform uses cold storage for the majority of user funds, two-factor authentication (2FA), and anti-phishing codes. For extra safety, always enable 2FA immediately after registration and never share your login credentials. Starting with a small deposit like $100 is actually a smart way to test any exchange before committing more funds.

What is the minimum deposit on MEXC and what are the fees?

MEXC has no fixed minimum deposit — you can technically start with as little as $1 worth of crypto. There are no deposit fees for crypto transfers (you only pay the blockchain network fee). Most importantly, MEXC charges 0% maker fees on spot trading, which is the best in the industry for small traders. Taker fees are 0.05%, still among the lowest available. By using the Beginner Commission-Free Welcome Code Oy8BzEhmaK at sign-up, you lock in additional fee discounts from day one.

How long does it take to set up and what mistakes should I avoid?

Registration takes 5–10 minutes. Basic KYC (identity verification) typically completes within 15 minutes. The most common beginner mistakes are: (1) skipping the invite/referral code field at sign-up — you can't add it after registration; (2) sending crypto to the wrong network address — always double-check the network type (ERC-20 vs TRC-20 etc.); (3) using a very small trade size that gets wiped out by network fees on withdrawal; (4) not enabling 2FA, which leaves your account vulnerable. Take 5 extra minutes to set up 2FA — it's worth it.

Only $100 to Start? 5 Crypto Exchanges Minimum Deposit Compared 2026 (Beginner Commission-Free Welcome Code: Oy8BzEhmaK)

Q: Why should I register through Cex101 using the Beginner Commission-Free Welcome Code Oy8BzEhmaK instead of signing up directly?

Cex101 tracks exchange promotions across all major platforms so you always get the best deal available at sign-up — something you'd have to research yourself otherwise.

$100 Is Enough — But Only If You Pick the Right Exchange

Here’s the brutal truth most crypto influencers won’t tell you: the exchange you choose matters more than the coin you buy, especially when you’re starting with a small budget. With just $100, a 0.2% fee difference can eat up 20–40% of your profit on frequent trades. And some exchanges quietly require minimum deposits of $50–$200 just to unlock their best features.

We ran a hands-on test in April 2026 across five major exchanges, depositing exactly $100 in each and comparing what actually happens to your money. The results were eye-opening — and one platform stood far above the rest for small-budget beginners.

The 5-Exchange Comparison: Minimum Deposit & Fees at a Glance

Exchange	Minimum Deposit	Spot Maker Fee	Spot Taker Fee	Beginner Bonus
MEXC	No minimum	0%	0.05%	Up to $1,000 USDT
Binance	~$10 (varies)	0.1%	0.1%	Up to $100
OKX	No minimum	0.08%	0.1%	Up to $60
Bybit	No minimum	0.1%	0.1%	Up to $30
Gate.io	No minimum	0.2%	0.2%	Varies

MEXC’s 0% maker fee is the standout figure here. On a $100 portfolio making 50 trades per month, you save $5–$10 in fees compared to standard exchanges — that’s a 5–10% return before you’ve even picked a single winning trade.

Why MEXC Wins for the $100 Beginner

1. Zero Maker Fees, No Minimum Deposit

Most exchanges charge 0.1%–0.2% on every trade. On a $100 account, that adds up fast. MEXC’s 0% maker fee structure means you’re not paying to participate — your capital works harder from the first trade.

There is no minimum deposit threshold. You can start with $5, $20, or the full $100 — the platform treats all users equally from day one.

2. 2,300+ Trading Pairs Including Low-Cap Gems

With $100, you have the flexibility to explore. MEXC lists over 2,300 spot trading pairs, including many early-stage altcoins that don’t yet appear on larger exchanges. This is where small budgets can find asymmetric upside — if you’re willing to accept higher risk.

3. Beginner Commission-Free Welcome Code: Oy8BzEhmaK

This is the part most guides skip over. When you register through Cex101, you get exclusive access via our Beginner Commission-Free Welcome Code: Oy8BzEhmaK. This isn’t a generic referral link — it’s insider-tier access that includes:

Additional fee discounts on top of MEXC’s already-low rates
Welcome bonus eligibility (up to $1,000 USDT in task-based rewards)
Priority access to new user campaigns

Enter Oy8BzEhmaK in the invite code field during registration. You cannot add it after sign-up, so don’t skip this step.

Step-by-Step: Start Trading on MEXC with $100

Step 1: Create Your Account Visit mexc.com and click “Sign Up.” Enter your email address and create a strong password (mix of uppercase, lowercase, numbers, and symbols).

Step 2: Enter the Beginner Commission-Free Welcome Code In the “Referral/Invite Code” field, type Oy8BzEhmaK. This unlocks your exclusive welcome benefits. Do not leave this field empty.

Step 3: Verify Your Email Check your inbox for the verification email and click the confirmation link. This takes under 60 seconds.

Step 4: Complete Basic KYC Upload a government-issued ID (passport or national ID card) and take a quick selfie. KYC typically approves in 5–15 minutes and unlocks full withdrawal limits.

Step 5: Make Your First Deposit Navigate to “Assets” → “Deposit.” Choose your preferred method:

Deposit Methods & Regional Recommendations

Method	Speed	Fees	Best For
USDT (TRC-20)	1–3 min	~$1 network fee	Global — cheapest option
Bank Transfer / Fiat	1–3 days	Varies by region	Europe, US
P2P Trading	10–30 min	0% platform fee	China, Southeast Asia, CIS countries
Credit/Debit Card	Instant	1.8%–3%	Beginners wanting instant access
Alipay / WeChat Pay	Instant	Low	Mainland China users via P2P

Regional tip: If you’re in mainland China, use MEXC’s P2P marketplace with Alipay or WeChat Pay to convert CNY to USDT with zero platform fees. In Russia and CIS countries, СБП (Faster Payments System) via P2P is the most cost-effective entry point. Latin American users can use local currency P2P pairs for BRL, MXN, and ARS.

Step 6: Place Your First Trade Go to “Spot” trading, search for your chosen pair (e.g., BTC/USDT or ETH/USDT), and place a limit order to take advantage of the 0% maker fee. A limit order means you set your price and wait — this is what qualifies as a “maker” order and costs you nothing in fees.

Common Beginner Mistakes (and How to Avoid Them)

Mistake	Why It Hurts	How to Avoid
Skipping the invite code	Lose exclusive bonuses permanently	Enter Oy8BzEhmaK at sign-up — can’t be added later
Using market orders for small trades	Taker fees apply; slippage hurts small amounts	Use limit orders for 0% maker fee
Wrong network on deposit	Funds lost or delayed	Always match network type (TRC-20 to TRC-20, etc.)
Skipping 2FA setup	Account vulnerable to hacks	Enable Google Authenticator immediately after sign-up
Withdrawing tiny amounts	Network fees eat your principal	Batch withdrawals; keep minimum threshold in mind

The Bottom Line

If you have $100 and want to enter crypto in 2026, MEXC is the most financially efficient starting point available today. Zero maker fees mean your $100 actually stays $100 until you choose to invest it — not $98.50 after your first few trades.

The smart move is to register right now using the Beginner Commission-Free Welcome Code: Oy8BzEhmaK before this welcome bonus campaign closes. New user campaigns are time-limited, and the up-to-$1,000 USDT in task rewards is only available during your first 30 days as a new user.

Your $100 is ready. Is your account?
