Did lot of ppl here got it at 3 cents and then able to sell it at over 30 dollars. That is insane. Buying 10000 of it only cost 300 dollars. That would be over 300k. So if someone bought 3000 dollars worth of 100000, that would been over 3 million dollars...
Thats not insane buddy if Nano was already listed in 2017 -2018 bullrun $30 dollars is very possible because im notice in that particular period all crypto's are going crazy pumping even the so called shitcoins are also pumping at that time even my few bucks holdings of ICO tokens are also quadruple in value. I think theres nothing wrong on CoinmarketCap data its just shown the details in that particular period.
