Anyone who buys in now is buying in at an all time high. Same was true in 2013, and those people would have made a good return, but it's super risky. But damn nice to see bitcoin above $5000! I'm ready to do a little dance, except I've pretty much sold everything I had. Oh well, easy come, easy go.
It doesn't matter i would still buy though 2013 ATH got broken and 2017 ATH will be too in future.Bitcoin price in 5 years will me much more then what it is today so for those who are for quick buck don't buy it but people like me looking to invest long term shouln't be worried.
