Just a quick disclaimer, I am heavily invested in this coin.
I discovered turtlecoin in it's earliest days, back when you could mine around 500k a day on a single nVidia 1050 GPU. I had already made a ton of free money, but decided to do some research.
That's when I came across the website.
https://turtlecoin.lol/ . I instantly noticed how well built and streamlined it was, which prompted me to do more research on it. I soon discovered the discord, which was growing larger every day, with more people learning about turtlecoin.
The devs are public, the Github is updated regularly, the coin has a low market cap, it's a privacy based coin and isn't on any decent exchanges.
I will continue to buy this coin until it breaks out, because it has all the tell tale signs of being way undervalued.
As always DYOR and only invest what your are willing to lose.
