@danizaharie, That would be best blockchain introduction about Springrole system. Incentivized Participation program is a better option to increase their membership and given cash incentive to direct to the member who invest there. They allowing complete transparency, low fees, and immediate crypto only transactions. Fully developed as a web, iOS, and Android app, WorkCoin delivers by bringing the benefits of the blockchain. Another thing is SPRING Token Ecosystem given opportunities digital product can find directly using Spring tokens. It's great thing there available. Need to check it out via link.
