I hope you are not blind trusting this youtuber, and have your own inputs.
Anyway, try in other communities as well. I don't think many people are familiar with that platform here.
If you want, you can try to tweak your risk level by depositing only low to medium amounts, so it won't be as damaging if things go shit. I keep this idea whenever I'm keen on trying a platform I ain't familiar with.
Just keep in mind that having a good first few experience doesn't necessarily mean it will continue to be in the future as well.
If an influencer invites you to use a particular platform, they likely work (on contract) for that platform or receive a share of the referral revenue.
It's best to consider the worst-case scenario; negative reviews often reflect the true reality.
You can check the rating for Bybit and Bitget on Trustpilot, it is also poor.
You can check the ratings for Mexc, Binance, Kucoin and some other well known exchanges, you can see it is very poor but not reviewed because Trustpilot displayed this:
This company’s rating is unavailable due to a breach of our guidelines.
Users do not like many of these exchanges. Any slight mistake, they will give the exchange a negative review. I am using some of these exchanges but they are not bad. I am not using Blofin but I just want to point out that it might be a good exchange.
Most well known exchanges are not having good reviews on Trustpilot, including Binance.
There was a time they had good reviews, but it changed to bad gradually.
