QoinPro was conceptualized and started as a side-project late 2013 as a crypto currency faucet. Daily miniscule fractional amounts of crypto were given to users to introduce them to the Crypto industry. People sometimes wondered about the business model, but it was ultimately a marketing expense to grow the userbase. QoinPro grew to around 1 million users in the first few years.
Several crypto currencies were listed/delisted during the first few years. The alt-coins that lasted the longest were Lite coin (LTC), and Doge coin (DOGE).
QoinPro has recently (early 2021) partnered with StartPage.Finance (SP.F) who have many more opportunities to earn Crypto with significantly more frequent updates. The difference is that although they do provide passive bonuses, most points (that can be redeemed for crypto) is rewarded for active participation and engagement.
Lesson learned: Always sustain the momentum.
Early support for transactions (deposits first, withdrawals second) lead to an increase in activity on the platform. While most users continued to use the platform primarily for the faucet functionality others started to use the wallet functionality as well.
Early support was only for UTXO based wallets. Ethereum support (with account based wallets) wasn't added until many years later.
