What happened? Why this price jump? Any news?
I wasn't aware of the block reward altering, that will have an influence but I was going to say alot of crypto could receive a benefit at present as BTC rises consistently for any period it creates a positive environment for price gains in a variety of alternative crypto blockchains. Its a recovery, some will have sold out at higher prices and wish to buyer lower here at least upto the point of the period prior to the major virus news etc.
Overall crypto should benefit from paper money being both physically compromised in possible transmission and also now as a standard undermined by alot of spending and lower interest rates, etc.
