It is very difficult to precisely forecast the BTC potential growth limit, but we will tell our opinion, based on some interesting notification.
Let's assume, that the 2017 year scenario will repeat. We had a base level (fundamental price) approximately $3800 for 2017. The huge growth phase lasted almost 70 days. Nowadays, if we look at this pattern, apply to the price chart, we will see the new base level is $10500. The potential target level is $25500. But it can be higher, if we calculate the new bubble highest high according to percent growth.
We need to wait the ATH level breakout, to make the new predictions.
