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?
Some of the best centralized exchanges are binance, kraken, bybit. They have an advantage in liquidity, but the disadvantage is that the funds stored on the exchange do not belong to you. Some of the best decentralized exchanges are dydx, mango markets, wowswap. There is not so much liquidity here, but you have full control over the management of your assets, because it works through connecting your wallet w/o having to make a deposit and go through the KYC procedure for trading or staking
