In my opinion, the coins that are worth investing in the long term are those who have a dance reference for developing it. Those who have a compact team and have a professional level of performance can be relied on to increase the value of your investment assets. By virtue, I believe in BTC, ETH, ADA, EOS, NEO. and also Waves. Their development continues to increase and its potential is good enough to continue to be developed to become a valuable coin.
