Now without going into whether above claims are true or not, my concern is "Isn't this is the right time to enter the bitcoin market or purchase few more". There is definite signs of improvement in the bitcoin price market. Current price is around $3757. It is quite possible to see bitcoin back to 4k to 5k or more. Given biggest players from finance sector are eying this lucrative market.
What do you think, is this is right time to buy some more bitcoins or wait and watch?
