Right now I have 100 WCT and 55 Waves coins and 0.25btc more...please tell me which other coins I should add in my portfolio for those bitcoins
Hold 0.1 BTC at least. For other 0.15 BTC buy ETH, NEO (for 0.05 each one) and Ripple, ADA, ETC, 0x, Strat (for 0.01 BTC each one)
All of that you've mention above are in the top of coinmarketcap and all are promising and the good thing here is the diversion of coins that needed to be done so when things turned out unexpectedly there's something we can still count.
You can also choose other coins in coinmarketcap if you like and still the most important thing here is research first the coin before you invest.
