While we can say that the future is uncertain for everything. With bitcoin, it's here to stay and we have to take that as a real fact. That bullishness for bitcoin is the same for me. I have no doubt for it in its future because for how it went throughout the years, we've seen how it's tested its resiliency. But I won't disagree even with it here to stay, the future is uncertain and only us can unfold it when we pass through the years.
Bitcoin is here to stay, I can not disagree with you but more than that, it will grow more. Even so, Bitcoin growth in adoption, value and price will not be rosy and smooth with time, as history of this market shows high volatility with bull and bear market, ups and downs, market crashes and chaos, people who are in this market with money spent for bitcoin will have to prepare for such volatile and wild events.
If they can go through such events well, and can hold their bitcoins without panic sale or market liquidation, they will be able to enjoy their Bitcoin portfolio growth in value. It's only matter of time and whether they can do their tasks well, the rest things belong to Bitcoin which will do its jobs excellently.
