Personally I am pro cryptocurrency and partake in it. With the down turn I sold a few graphics cards but still have 8 GPU, an S9, and L3+ running.
People can crap all over bitcoin if they want but I think their opinion would change and will change as it advances and they use it. I sent 2000$ USD to China for 0.06$ with out having to ask a bank or seek permission. Is it perfect, nope, but it is software and will improve. In the mean time I will continue to mine it and make the odd trade.
It will be interesting to see where it goes but I suspect it will earn a place in many portfolios as time progresses. Just wish I had a better income and could stack up more gold, silver, and bitcoin.
