Investing your bitcoin takes a risks, anyway all investments
are in risks. But, its a matter of how you manage your money
well. It's a good idea also that you invest your bitcoins like
trading, and other investment sites
I think investing in trading is better then investing in any investment sites as we don't know how long those sites will survive and if it disappears in future then it will bring huge loss for us resulting in loosing our investments.
Trading is not investment, its a job. Investing is put your money for work and get return from them. And some people use trading as gambling and think they are skilled because they profit until they lose alot.
