For me, I think if bitcoin never reaches the all time high, mass adoption wouldn't be developed and the reason why people are investing in bitcoin is because they saw that bitcoin can change people's lives.
So you mean that the only reason for Bitcoin adoption is speculation? Aren't you a bit harsh?
One great thing Bitcoin can bring is to avoid the need to exchange money in all the local currencies and pay with Bitcoin.
Another great thing is money transfer way faster than any banks would ever do.
Also don't forget its main feature: set you free from centralized and politically manipulated fiat currency.
All of these mean nothing to you?!
Its price is volatile in the market it goes down and it goes up and that's what makes bitcoin very hard to manipulate.
Don't you think that this up and down can be the result of some manipulations and can make some traders very rich?
The price is really unpredictable and it takes a great prediction and strategy for you to prevent having huge losses, but it still depends on how you can recover from that losses.
It's hard to predict, but professional traders may do it. Trading is not for everybody and many treat is like lottery.
Overall, bitcoin is really a good store of value, it can bring you a huge amount of profit when its price is in its peak. You're so lucky if you experienced the all time high of bitcoin as it is like a lucky day for all of us who uses it.
Many bought at peak. I would not call them lucky. And Bitcoin as store of value is quite a debate which is affected a lot by its huge volatility.
All in all, I think that you should read more. Many of the things you wrote are incorrect.
