Coins for long term, i look for teams with good development team and a future with proven tech. Bitcoin is finally getting its shit together in 2018 :)
Bitcoin cash is onchain mania. While i support the LN everyone in the bitcoin core community knows we will have to hardfrok one of these days but we have some many other tech like one tech that can make 100 tps in 1mb blocks onchain so it good.
Plus bitcoin is getting it eth killer: rsk.co
Other coins:
Neo=china gov support
Ripple= hate it but it going to go up bc of banks but i hate it. :(
Eos is looking good.
Monero is getting a huge upgrade :)
Dash is ok. Their insta send is like an onchain LN.
Golem is cool.
Kin has potential.
Particl and tenx are in my bag.
flyp.me is look kucoin but in a form of shapeshit alternative.
