The initial coins I have interest in mining/trading are as follows:
Trade: GAS, NEO, VERGE, XVG, XDN, ADA, MED, RIPPLE, TRON, LTC, BNB
Mine: BTC, ETH, LBC (LBRY), ZCASH

1) Which website/s do I use to open a wallet for each of these coins?
2) Where do you recommend I store these wallets?
3) Coins I purchase to hold or trade has to be bought as a pair? How do I know which symbol goes first on the pair?
4) To my understanding BINANCE is the exchange to be in but I heard that I first had to open an account with BITTREX then move my money/coin to BINANCE?
5) Once wallet/s and trading account/s are open I was recommended to buy Tether to hedge my USD and prevent it from BTC's volatility. Does this mean to buy BTC/USDT? If yes, does this mean that once I'm done trading alter coins to always buy back BTC/USDT?

In a nutshell, I would like to set my wallet/s know the safest way to store them and have the exchange accounts open to execute trades or open positions...


Thanks for all you guys input!
