Everyone talks about blogging, commerce, using referral systems, bounty, campaign signatures, streaming, selling courses, offering their services in gaming, camwhore. But there are other not so known ways to generate/earn cryptos?
Do not have an exceptional view on cryptos, if you have then you might be thinking there is a hidden way. Cryptos are nothing but money and earning cryptos will be possible all the methods we are using for years. I mean to say no special ways required to obtain cryptos. You may earn in big number if you work hard and invest responsibly in huge amount.
One know method for earning millions in cryptos is operating a cryto exchange in friendly manner. But, it requires at least half of the million dollars and up to 20 people to dedicate their all the hours. Simply, there cannot be any less-known method legally but there can be hundreds of illegal ways and I am not ready to discuss on them.
The easiest way to earn in my opinion is by staking pos coins. That's as close to a source of passive income as you could get.
Compared to master node coins, I also recommend to go for POS coins for passive income generations. Also, freebitcoin is providing 4% annual interest rate on daily basis. There can be such methods but all are good for passive as most of them are low in earning still good for long term basis.
