I think it depends on how you deal with it, bitcoin is a good investment for long term many people still don't earn on holding it because of the patience issue, they will not holding it tight in terms of trouble or bear season, but i believe that if you have a very big patience you can get a lot of profit in BTC i dont think that it can make you an independent but i am sure there is a profit on it.
There isn't only profit in trading, but you can gain certainly depending on your strategy. Trading isn't even guaranted to earn money it only depends on every person and their way of thinking since every trade is always a gamble and there will always be risks. That only depends if someone also accepts that certain risk, this is why people tend to be more hopeful once they are also shown big amount of money as a bait. This is what most influencers take advantage of since they knew people will bite the bait just because they are shown someone's income. From their own perspective, it's a big amount of money although it is too good to be true.
