Bitcoin and ethereum prices will fall hard and stay down for a while. This is my prediction. Sad Panda will witness bitcoin and ethereum enter a pretty unappetizing bear period as the current bull period is inflated by confidence/speculation. A big cash out before the anticipated 3rd year slump hits which will create a dramatic fall in prices. With ethereum going to proof of stake, the cost of electricity and gpu investments (nvidia is a moving part of this machine) will no longer back ethereum, currently a really big player.
Watch out for small alt coin scams and selective scamming exchanges - not really a new thing, but more people will become victims.
"Jiang Zhuoer, one of China's big miners, told WuBlockchain that according to the latest multiple model studies, the fastest will be September 2021 and the slowest June 2022 will turn from a bull to a bear market." This is in line with my prediction and also lines up with the bear/bull cycle of bitcoin. As over 60% of bitcoin is mined in China and this guy represents a big pool, I feel he has his ear-to-the-rail. However, I do see this bear as being a pretty nasty one and recommend hedging yourselves. Right now bitcoin is at $52,500 (fell from $57k today), but I'm not sure I'd assume its going to fall to the earth yet. It probably has a good percentage of return left in it for a few months.
