ya it is true that altcoin mining is very much profitable even new coin also if you mine and when they hit exchange you can earn in short time, other then that you can watch in altcoin announcement section where you can get free coins for social media bounty . so their are so many passive income, only thing is you have to be active to grab them
Getting altcoin from bounties is not passive income since you still need to make an effort in order to grab them, and while altcoin mining is profitable, mining new altcoins is a risk since the coin could be dumped very quickly without giving you a chance to sell your coins and recover your investment.
yes that is a fact that income from a bunty campaign is not a passive income, as you work for it, you use your time and full effort for it, i think there is no way of passive income.
