I do not buy a lot of coins. I invest in ethereum, ripple, eos, waves and NEO. And, of course, I dont go around without a bitcoin leader. I think this set of coins is the most promising.
I have the same strategy, i prefer to stick with some trusted projects like those you've mentioned rather than searching for something that i won't be sure of - i just don't have enough private time for this right now.
Good choice. Altcoins are far more interesting investment target than Bitcoin and other coins at the top of the market. There are not only more profitable, but their developers used to have a fresh view on market situation. It is definitely wort to support them. I'm investing in alts too, currently mostly in Neo, Dash and FuturoCoin (its developers have recently updated its masternode system, so now you are awarded with some passive incomes when you are a masternode owner)
That FTO changes in their protocl are crucial to their future in my opinion, it's very interesting project, so i wonder what is their move. And whether it comes to bitcoin - well in my opinion it truly depends, cause bitcoin still can be very profitable, especially when it comes to new bitcoin-related projects, but recently i also rather invest in altcoins.
