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

They are all good and there is every possibility that you can do all of them. There is nothing much to do in lending, all youve got to do is find a good project and lend your money to them and hope for when they will return it with the profit you have made on top. As for trading, it requires a lot of training cause if you just jump into it without training, you will just end up losing your money.
Then as for ICO, I dont really need to talk about it cause you know how it works. Same as bounties, if youre good enough in managing your time, you can do all these and make bigger than you will do while relying on one only.
