In a way any market that you can trade in are the same. You can only make profit if you can speculate in that market by knowing what affects it and will lose money if you enter it blindly.
But the difference that bitcoin has from other markets is that it is on an adoption path which means its price will always go up in the long run. Unlike stocks which don't really have an "adoption phase" and can only go up if the company is doing well or the economy is good.
I have seen that Bitcoin is always goes in bull and also bear market seasons and in these cycles only big whales are earning and they wil be always be millionaires.
You don't need to be a whale to make profit, you just have to be wise.
But in Stock market that has lasted almost decades to centuries and I do not know if they have also been going like Cryptocurrency market.
The cryptocurrency (aka altcoins) market can be compared to penny stocks market which is a small market that lists shit stocks with low value and most of them have no utilities and die sooner or later. Altcoins are the same. We also have the market manipulation that is dominating the altcoin market because it is not regulated.
I think that united States dollars was in bearish for many years when Us Has war with Afghanistan.
All fiat currencies are always in a bear market simply because there is an unlimited supply of them. In other words the governments keep printing them so they lost their value over time.
And now I think it is in bull run season for many years though United States economy is not too strong.
Considering the inflation in US and how price of everything is going up, US dollar could be considered in a "bear market".
