Cryptos are definitely riskier than stocks etc. but if you know how to use information in your favor and research you can gain from this swingy market. My guess is that about 7% of winning standart traders are profiting long term in crypto markets. Leverage trading is the best tool to pain and gain. You have to be a gambler in other words and starting without good instructors and sources you will end up broke. By investing = hodling you just park a car and look how its get driven. Do you wanna drive?
I have been trading in both markets and I can say with certainty based on my experience that crypto is more volatile and riskier but highly rewarding. I know many crypto enthusiasts who made huge amount of money by airdrops, joining bounty campaigns on Bitcointallk without making any investment. Volatility in any market is also an opportunity to make profit if you know how to manage risk and that is the key of success in any market.
