I know there are several of the CTP and Alive Community that uses LeadsLeap as their autoresponder and list manager. Credits earned on LeadsLeap can be used for Advertising or can be encashed (cashed in) for Crypto.
Especially for the participates of the Larry Is Alive challenge.
Currently LeadsLeap is offering double Encash Value for your accumulated credits. You can trade in your credits (minimum 50) once every 24 hours. If there is a good response to their offer, they will start offering this deal more often.
I try to encash on a daily basis to get additional funds to move to the Hive Platform. I then invest the funds in various projects and earn additional passive income from these actions.
In addition to credits for advertising, you get earnings for your daily activity as well. I group these funds with my encashment funds and move them over to Hive as well.
For those that do not want to move the funds to Hive, withdrawals can be sent to any crypto wallet.
