If you missed out last year on buying bitcoins when the price was low, then you are getting a new opportunity now to buy at a very low price. We always say, buy LOW and sell HIGH, but nobody listen to us. They do listen to the sceptics and the trolls and they panic too quickly and then they want to come back here and complain to the people who gave them good advice.
Exactly. We spent the first part of this year with people complaining that the price went up too fast, that they didn't have enough of an opportunity to buy, that they didn't own enough, that they wished the price would fall again so they could buy more. Then, as soon as the price does start falling, the same people panic. Not only do they not buy more like they had wanted to just a couple of months prior, but they also panic sell and declare "bitcoin is dead". And then come the next bull run, some of these people will be back, buying in again at a higher price than they sold at, and lamenting yet again that they missed the low prices.
If you believed in the fundamentals of bitcoin and its potential for mass adoption at $20k, then I don't see why you shouldn't still believe in it now. If there has been some massive technical failure which I am not aware of, please do let me know.
