If you're in the USA and don't have over $40k, things are going to be harder for you. USA is fucked with regulations so you guys don't have good exchanges to buy shit. However, if you got decent money, you can use Uniswap but that ends up costing $20-$200 per transaction so you're gonna end up burning a lot of money that could have been useful.
Harsh reality, it sucks. I am sorry though and there are ways to still make this work for you.
To be honest, if you have those 2, you're pretty much set. The potential to find 30x-100x gems in those exchanges are gonna be very high in 2024 and 2025. You're not forced to used Decentralized exchanges to make serious money. However, 1000x and shit will probably be limited to DEX but that comes with extra risks and money burning obviously.
But there is a way Americans can POTENTIALLY use the good exchanges, legally. I will need some to verify this and will get back to you guys in some time.
