I have placed my orders. Thank you everyone for your advice. I put my money on XSPEC, VIB,ZRX, SHIFT, QRL and (very little) DOGE. I don´t think I will reach 10x in short terms or maybe ever.
I don´t think it´s possible unless you are very lucky and get a lucky punch or invest very much time in research and even with every currency checked its developement is uncertain I guess.

So I hope for the best, prepare for the worst and check back in two month;-)
