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

I guess several such topics have been created untill now and this question is been answered several times.
Considering your rank, i think you are a bit new to the cryptos and also to the forum.
There are a number of ways to make profits in the field of cryptos which includes some major ways like trading, mining, etc.
The ways you mentioned are also much profitable but some of them are a bit risky.
Considering ICO investments, it can prove a bit risky as some companies simply run away after they recieve some funds from the investors which does not at all give any kind of profits to the investors.
That's right, I've had a few of those projects that just run away with the profits and deceive investors. I think in this world of crypto there is a lack of maximum security
