Hello and welcome to Steemit. EOS is an excellent choice for a next generation cryptocurrency to own. You can check out the EOS.io website to read the whitepaper and get more info. Also if you download the Telegram messaging app their is a channel called eosproject with almost 25,000 members to answer your questions. As far as exchanges go I prefer Binance they are the largest exchange by volume in the world and also one of the few accepting new customers.
