As you can see, the last time BTC had an RSI this high and started to nosedive on the weekly was at the end of 2017. It is possible that it will just keep diving up and down and staying near the very top of the scale but I personally think we are going to see another decline and a new low not seen for years. We all know the saying, "Fool me once shame on you, fool me twice shame on me." I think the people who were predicting a new ATH got fooled twice. The thing about exponential growth is it isn't sustainable. Eventually you'd need more than all the money on Earth in BTC to keep growing and I think a lot of people got burned at the end of 2017 so new ATHs seem quite unlikely.
