A week or two ago i was about to donate sens a small amount of money that should then be tripled. I haven't done that because i have gotten aware of transaction fees that middle men charge for their service and the awareness that they are already made unnecessary by cryptocurrencies which utilize blockchain technology that renders any middle man obsolete. Bitcoin is the premier cryptocurrency and accepted by an ever growing number of companies, stores, individuals etc.
If sens or any anti aging organization wants to they can just simply download a bitcoin wallet, post their wallet receiving adress on their donations page and receive donations from any other with a bitcoin wallet of their own, nearly instantaneous, without losses due to transaction fees and very secure.
I mailed them but i didn't receive a response yet, but here i want to bring this opportunity under the attention of sens and the anti aging crowd.
