One thing I want to share apart from adoption (which is the main thing discussed here), that bitcoin is NOT a cash replacement. It is hardly a digital gold, which it is trying to prove.

The reason why people invest in it, is the parabolic price movement. personally I fell, at this point investing in bitcoin is at a very low risk, compared to if someone had invested at 17k $.

This is coming from the fact that from 19k, the price has gone as low as 6k then currently at ~ 9.5k. This is the accumulation phase. Although it is very likely to hit a fresh all time low. But even so, BTC is known to bounce hard. So I am very comfortable to invest at this price point.

Overall I am bullish about BTC. Here are my reasons for it:
