I’m relatively new to crypto, and I tried to look online first, but didn’t find an specific answer for this: so I withdrew all my coins from Binance, as tokens, using BEP20, cuz it’s cheaper, for e.g. compared to ERC20, but I wonder, what will happen if B

If that ever happens, Binance going out of business or banned from my country, how could I be able to swap, for example, ETH back to ERC20, or ADA to Cardano Chain (using a fairly user friendly way)? I know there is Binance Bridge, but if the exchange goes out of business won’t this go too? Or even worse, Smart Chain disappears also (if that is even possible)? I don’t want to stack my coins, I don’t want to have wallet apps for each coin, and Smart Chain seems to be pretty cheap and good, that’s why! So, are there also other exchanges that support BEP20 tokens (or would that end too with Binance ending)? Anyways, thanks in advance!
