I use Coinseed, though it's interesting; I have had to convert my portfolio several times before I found a good one. I found that app thanks to this community, actually. Not sure why, though I do find that changing the portfolio is the only way to invest in cryptocurrency. Then again, I'm no finance geek.

It's a small investment fund, without a professional manager.You are a manager.
That's what I'm suggesting to beginners, just an even greater factor of diversification.
It will be even better when someone organize a "real" investment fund with eg 500 crypto currencies, and offer others a sale of "equity shares" in such a fund.
Even more security.

If anyone actually ever decides to do that.

It's just a matter of time.
As with stocks and other securities.
