There will be no such success in bounty as it was in 2017. You need to accept that. Now you need to choose projects for participation very efficiently and do not put high hopes on them.
it is true that there will be no more projects like that in that year, because the projects in that year were all of a large success rate and the bounty hunters made a lot of money that year but now it's different again it's hard to find projects that can make a lot of money again
A lot of people Invested in cryptos in 2017 those projects then reached both Hard cap and Soft cap easily and became successful with help of the bullish sentiment of Bitcoin however I don't expect a replica of that scenario this year, I would prefers investing in the major cryptos like btc and eth.
