I'm new in cryptocurrency.
Have been lurking this forum for last week and also did my first investments.
I have invested in:
GNT
GAME
STRAT
TRST
SC
WAVE
I bought them at Poloniex and Bittrex. Is it safe for now to store them there?
Or should I store them in separate wallets? I'm new, so It would be harder for me as I have to create a new wallet for each currency. Or is there any other safe alternative that can store everything? I have heard of Jaxx.
Also, you can discuss or suggest me about my invested altcoins. Do you think they are good? I have profited from all of them for now except for GAME cause I bought it right at the highest bump for about 3$ and then the big crash/dump happened when everything hit red. I, of course, didn't know about that would happen cause I started to read about crypto on that day, lol.
Any tips are welcomed

of course poloniex and bittrex is save because every traders which doing trading in poloniex and bittrex doing the same like you. but if you invest for a long term, i think you need to download some multi wallet in your personal computer or your android phone and then you can send it into that wallet until you decide on how much price you want to sell. but if you only doing daily trading, then its fine to save it into poloniex and bittrex wallet so you can right away to sell it when the price is up.
