Is there a reason why you don't have BTC, ETH, LTC, ... in your portfolio ?
Same thoughts.
The only reason is that I believe coins such as NEO has a higher growth potential. I know many of these coins are more risky than ETH, but I have only invested money that I can afford to lose. That being said, I am planning to buy some crypto each month - and I believe most of that will be ETH.
You can also afford to invest money with bitcoin but the only thing that you will get is fewer since bitcoin's price is very much higher than those. So the answer to the question that you don't have BTC is because you are only believing to ETH, NEO and other altcoin as well but not with bitcoin?
Bitcoin is relatively cheap right now so even if the profits with bitcoin will be less than with other coins it seems worthwhile to invest in some bitcoin, you will get easy profits without too much risk, the rest of his portfolio is fine, but I will prefer to make safer investments especially since he invested a sum of money that is considerable to me.
