I will invest the Bitcoin to ethereum, EOS, TRX and LTC. These are most promising coins and we can expect the growth for long term most of the time our investors comes with different investment strategy for short term trading.
For long-term we can plan like this and invest the hard earned into these coins to have good returns in future.
I cannot argue with you that the coins you listed are very good coin, if these are the only coins that one even diversify to after bitcoin, I think we can rate the portfolio of the investors as 90 percent, but I also think that there are some coins that will really rule the market in the future, and these coins are these privacy coins, people will really get exposed to privacy coins as they are the ones that really have very similar thing to bitcoin, so they will work along way with bitcoin in the future.
One of these coins that I am targeting is Monero, this coin has been a very effective coin for a long term now and has really been serving its community very well when it comes to privacy coins, so this could be added to the list of the coins that you listed, at least one privacy coin would be okay.
