I am truly amazed it went from 10-1000, and i really don't expect it to last forever.... then again, Adobe flash is still a thing coming close to 2020.....
ETH has been talking "move to PoS" for years, nothing significant has happened.
I figure they'll take years to make an algorithm change as well, IF it ever happens.
Flash is FINALLY slowly dying, as new sites are largely going with HTML5 instead and some old sites are converting.
THANK GOODNESS.
