Maybe we can say right now is the end or game over for bitcoin and altcoin, how come bitcoin at last end year could be on $15,000 and now have drop lower than $4,000. You can left or stop investing your money at bitcoin and wait until bitcoin price is higher.
Because BItcoin is volatile. Bitcoin isn't lower than the price it was 2 years ago. Bitcoin is inherently volatile, so while I think the fear is warranted, it's also blown out of proportion when you consider the value 2 years ago.
Let's face it, people got really excited w/ Bitcoin jumping to $25,000 - they invested thinking the rise would continue, and reality set in. That doesn't mean Bitcoin is "dead" or going to die, it just means we had to go back to reality for a bit.
This is why I always feared the massive increase up to $25,000 wouldn't be a good thing. It gave people unrealistic expectations, and gathered a crowd which was going to run when the value of Bitcoin was going down. I would have preferred a slow & steady increase over time, not the dramatic increase as we saw before.
