Buying coins on multiple platforms?

up until now i have only been comfortable buying off Bittrex. since doing research on coinmarketcap (which i just learned about on here) i have been looking for certain coins i cant find on bittrex. say for instance Medibloc MED. im either searching wrong or they dont have it. which platforms do you all buy/sell/trade using that you feel comfortable with and find reliable? I have had great success with Bittrex im just wanting to buy a few other coins i cant seem to find when searching.

Also, i cant find a post someone put up the other day regarding how to find out about ICO's? there was several links to sites that talk about new ICO's coming up. Does anyone know any good places to look up and learn about ICO's?

Thanks in advance.

oh and last but not least, there is really a coin called tittiecoin TTC? lmao
