Tomorrow is a monthly closing and most currencies are Naima
Even better this moment in order:
Dgb
Xlm
Btc
Etc
According the coins you've mention BTC, ETC and XLM are really the good ones especially for long term there are a lot other potential coins than DGB like ETH, NEO, ICX etc. just do your own search other than asking other people opinions here and for you will know it. Goodluck.
