If you'd been in Bitcoin over the past 10 years you would have witnessed at least five 85%+ drops and still be up over 300,000%.
What's your point? That 85%+ drops in value are a reasonable thing for a currency? That a 300,000% increase over 10 years is a reasonable return? These are two sides of the same coin telling the glaringly obvious tale that: Bitcoin is an absolutely awful store of value.
States think positive inflation is good, because it's a hidden tax that they profit from. I think 0% inflation is better for all participants.
Yes, I think growth in waves is a great start for a money. Same thing happened with salt, gold, and other commodity monies.
I help my friends buying Bitcoin and I make sure that I prepare them for the huge risk they are taking.
The most brutal things for me were about losisng/forgetting/not writing down correctly passwords, exchanges being gone with part of my money, even though I tried to be very careful. Being 80% down is nothing compares to.these kind of (not as rare as you think) events.
