This is the primary crypto exchange I use It is also the first one i ever used although I use multiple exchanges I believe it best to stick with just one until you become more familiar with crypto
Web browser with built-in bit coin miner its simple its easy its a little slow on basic free tier but it works and it is fully compatible with chrome extensions.
.
Brave is another Browser that integrates Crypto and much more focused on privacy and owning your private data your self Highly recommend.
