Use binance imho. it just works fantastically well.
As for checking on the blockchain you can just google "bitcoin block explorer" and then enter the wallet address there in the top right.
The exchange will say how many confirmations they require, some require 2,3 or 6. once the blockchain shows sufficient confirmations the funds should clear out.
Hope you can get your funds back from rightbtc.
