This is newbie talk, so don't kill me. I want to learn, but it seems so complicated.
I want to - sell BTC for ETH, and then sell that ETH for more BTC than I started the trade with. Sounds like a simple way to start, yet I know it won't be.
My biggest concern is that there are so many exchanges. How the heck do I know which ones will pay me after I make an exchange? I know I have to check their reserve balance, but what else should I look for?
I think the best choice is to use the proven and trusted exchange,example is houbi and kucoin or binance, there are a lot of new crypto exchange today and the only way to avoid being scam is to use the trusted one, because we dont know if the new exchange is scam so i prefer to choose good exchange for good.
The safest is to use a trusted exchange as you mentioned above,
the exchange is unquestionable and it is a popular exchange too,
from the level of security it is also safe and has been proven to be better to minimize risk by choosing a trusted exchange like Binance and others
