Why did Bitcoin raise past $30,000?
____
I don’t know why Bitcoin plummets, but it seems to be a gamble with all sorts of currencies.
Any suggestion would be appreciated.
It rose past $30k because it is in a bull run driven partially by last year's halving and partially by institutional investment.
___
The reason for it plummeting when overextended in a bubble varies.
In 2011 it was MtGox being hacked.
In 2013-4 it was rumors of China banning Bitcoin, combined with MtGox imploding.
In 2017-8 it was simply a matter of over-extension.
In 2020 it was Covid-19 which also crashed most of the other markets.
That was the last time it plummeted. What happened a few days ago wasn't a plummet. It was a little correction which, as we saw, didn't last long.
___
My advice to you is to hold your Bitcoin steadfastly, resist panicking if the price goes down, and wait at least 5 years.
If you want to gamble your money by day trading, don't be surprised if you lose it.
