Coinpot was one of the most active and famous faucet collector, a site where users were able to gather all of the earnings they made from faucets and convert them. They brought to the faucet market a lot of innovations and features, such as a powerful referral system, a multiplier feature, gamification, ranks, and much more.
The reason for the shutting down is in a letter on the site: basically Coinpot was a amateur projects of a group of Devs. It's now taking away too much of their time and it requires too much effort. The team developed some good tools for anti fraud management and they will build a company or something over this knowledge, so from the ashes of Coinpot something will be born.
I guess it's an end of an era for many cryptolovers like for me. Even if was not using it anymore, Coinpot was one of my first source of Crypto earnings. It literally was my gateway to the world of blockchains: owning my very first satoshi was a real push for me to understand what crypto was about. I started studying how to transfer and manage them, I started noticing price movements and thinking about a strategy and what I wanted from cryptos.
