Sure he tweets every time he pumps it up but are you confident he’ll give you (and all the rest of his followers) a heads up before he dumps it? I wouldn’t be. And for that reason alone it’s a fatally flawed investment strategy.
he just has to tweet something remotely bearish and the market craters
The last time he cracked a joke about BTC maxis and sure enough, the market dumped. When he talked about BTC's eco impact, it dumped hard as well. You can trace the pumps/dumps to the exact moment of his bearish/bullish tweets.
