For now his second time is not good because Bitcoin has decreased and some Altcoins in Bittrex have been eliminated from Bittrex side.
But I suggest it to hold Altcoins who are in the top 10, such as TRON, Ethereum, EOS etc. Because their financial foundations are so large that they are safe to HodL.
i think both of them are very useful to earn only difference is from day trade you can earn on daily base and from hold you can earn after some time.
