Just one question, do you trust in Stellar? If you do, then just invest, it is one of the most safest coins at the moment since it is just like the Ripple 2.0, so there is no problem at all.. But it is plenty of good projects at the moment, and more profitable ones, why do you really prefer Stellar?
I need some advise to know which coins are a good to go so I can invest some of my weekly money and probably make some money on the future.
