Raiblock (XRB) A.K.A NANO.
From this alt-coin, I finally know more about Cryptocurrency. It's super easy and free for mining this coin on the olds day, you just need to solved captcha for the coin. Finally this coin making the big success by listing on Binance.
It's crazy.
I remember this coin a.k.a mRai if you are familiar with it
In early 2016-2017 where everyone make a commission-based payback for every captcha you successfully solve, so many people joined this from just regular captcha solvers to big team to solve the captchas. It was really nice experience to be part with it especially with the amount of you'd get that day which is really high compared to any bounty you find here today in total.
For me AVAX (avalanche) Is the coin i got good profit in this coin by investing 5 times.
First two times i got huge profits.
But after that not huge but that was also the good profit by holding same coin.
Made huge profit from MONACO and
of course the website is already downFirst launched in 2017 where the ICO of MONACO was a huge success and you could literally make 10 - 30X of your ICO investment when listed on exchanges, it was on Poloniex as far as I remember. Pretty good year I would say for ICO compared to todays standard
