almost like gold holding bitcoin is a profitable investment because the predicted value will further increase annually just don't panic when its value fell even at the moment used to rebuy bitcoin because most likely the higher value will
I agree, we can look back at the history of Bitcoin. Those who bought at less than a dollar and hold had been a millionaire when price of Bitcoin goes up 100,000% + times. And considering Bitcoin market is still young, adoption is still young and market has not been saturated, we really can be sure that Bitcoin will go up in the future. So holding it till that time come will certainly give us a good profit.
The price will continue to go up, but the main thing is that the higher the price is, the more it takes for the price to move forward. In short, the returns that early adopters have managed to realize, will not be realized in current times anymore, unless the price happens to rocket up to insanely high price levels that grant you a growth of x10-20 from current levels. I personally prefer to remain more conservative and focus on reaching $2000 first. This already will form a massive challenge with scaling debates still not being settled.
Making a profit from long term saving in bitcoin proves to be dissipating every day since the price goes between up and down really quickly, saving long time proved to be good for people who invested in bitcoin a long time ago, right now short term is the best at making profit.
