From the very beginning in 2009 bitcoin has always been appreciating in value during time despite all the crashes and it will continue to appreciate no matter if billionaires around the world keep playing with it.
One day 1 bitcoin will be worth 100k or more, it is mathematically designed to be a scarce resource and the market seems to consider it the store of value of all cryptocurrencies. All the bubbles that may occur don’t matter unless you are a short term trader.
