Because Bitcoin is a Ponzi scheme that will hit a brick wall soon and will totally destroy most folks' wealth and they will laugh all the way to the bank with the gold you sell for fake value. Bitcoin is not private, and is accepted by the most evil people now...the very reason the whole crypto thing was started, to end the fed. So if you want Privacy where it is the only crypto that can't be hacked by the NSA, then consider the Monero way....totally private AND morally right. They have a big nerdy programmer following that fixes things FAST because they are on a mission. Etherium has no real programmer support, just a copy and pasted java script that is hackable. I am amazed that so few consider the building blocks and the moral of a coin...just the advertising and promotion levels. Research the reasons for Monero and you will find that it can be very cheep to move around or HODL if you believe in something.
