Dear friend,
So far, I know for kind of earning money from bitcoin and altcoins.
I start trading when bitcoin 17000. until now, I lost a haft of money.
ICO I have win any ICO. But I did not invest to much.
Lending I think have not join anyone. But I think in the first time you can get profit from lending. But no more later.
And now, bounty, I still reading and research information about it. No one help or support. One day, hundreds of campaign public. But dont know which one scam or good.
I am distempered. Need more advice from you here

It all depends upon whether you understand the crypto market or not otherwise loss in crypto trading is somewhat certain. Crypto market is very volatile and if you have no knowledge of how it works, you will loose tons of money for sure.
Most of the ICOs out there are probably scams and you need to check and verify many things before investing in any one of them to earn profits.
Doing bounty and lending your coins are two of the safest options out there to make money for a newbie.
