Yes, i fully agree the fluctuation is insane some days it is $700 then the other it will go to $500 you can just never really tell when it comes to btc but that's also the exciting part about it, gambling gambling pretty much.
You gamble with BTC then take a gamble with the stock itself.
Yes that definitely is also a big problem but i doubt that it is a main issue, that is what people really enjoy, the rush of the fluctuation and such so you cant really say that because thats why some people even use btc.
Gambling like that by gambling the major fluctuations is not a bad idea but you also have to know if you invest you're bound to make more money. You have to look at people that want fast and slow profit.
If you invest you probably would make more money but that's really dependent on the certainty that you'll make some profit out of it and there is no certainty to make money out of btc and i think that's one of the bigger issues for people that use btc daily.
