Most of the bounties are worthless.
You spend your time but at the end you are being payed 10 shitcoins with a value of 10 cents.
Of course there are also nice ones like Storm, Rebl, Sugar, INS etc which made the bounty hunters make several thousand dollars.
In order to prevent the waste of time I don' t partecipate anymore to simple twitter, facebook, telegram bounties where there are lots of participants with 10k followers. When I find a good project I directly join the signature bounty and support the project to be known in this platform telling about the projec.
Up to know I have not invested any money into crypto but my time.
I made a few hundred dollars till now and at the end of the year I hope to reach several thousand dollars.
