Which crypto do you trust more, the one that is traded freely and nobody knows where the rate will go tomorrow (like Bitcoin) or the one that is under control of its developers (like Ripple, more or less)?
Where you would invest?
Invest in a coin that already has a large volume, like 10 coins over the CMC. Every investment has a risk, but if the coin already has a large volume and a large community, I think it will reduce the level of risk. And this thing I do and trading is very profitable. But of course the market conditions are volatile, so I also suffer losses.
Investing in development may have huge risk. And for now, I do not invest in the project.
