If you really want to earn you should take the risk, trading is also high risk if you don't know what to do. You have prediction thay it will be 500.000/btc then why not to hold the coins? No risk at the same time.
it is the risk of each job. but for me trading have less risk than playing gambling. in trading we will not lose all the money we have. maybe at most only about 20% to 50%. I would argue that investment in trading is safe. each person must have a different opinion.
