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.
Oh I remember those days about RailBlocks, 2017 how to get and exchange here in the community and then it surges to like 50% or more when it changes it's name to Nano.
For me is ADA, (before this whole privacy centric thingy that they have done now), very cheap in the beginning, but one of those who had a good run during the last bull run. Ethereum as well in 2018 bearish market, it went low below $80 invested some and then went crazy on 2021 as well.
