Most of the time I only believe in bitcoin, because bitcoin and blockchain are our future applications.
At present, most altcoin looks more like a scam and hype, which worries me.
I agree, right now I trust bitcoin more than most of the alternative coins out there right now. Who really knows what cryptocurrency will be like in a few years time, all we have are speculations to go off of. Yes the things the author listed are reason enough to pull out of cryptocurrency but I see blockchain technology and the concept of cryptocurrency potentially changing a bit of things with our economy.
