Well I was all in on ethereum, but it can't scale. The developers say they have casper, but no one has audited the code. Bitcoin will be adding segwit a proven technology that is already being used on some coins, and hopefully lightning network which lite coin already has.

For anything to scale you need speed and inter chain operability, otherwise forget it. Ethereum is looking more and more like myspace. In crypto always go for the best technology, coding, and follow the programmers. Never fall in love with anything.

All the currencies i have listed all have good technology behind them and real world uses.

For wallets some i have paper and some on ledger nano s. Good luck!!
