I don’t request anything from my visitors and the users of the software I develop. All the programs, games and applications in this website are free and portable. I have this option for those who would like to donate in order to show their appreciation. Donations mean more frequent updates, more free applications and better web hosting. I only accept cryptos since I believe in them and the fact that they will appreciate in the future. Recently I discovered Algorand which has 0.001 transaction fee and funds arrive in seconds which is very convenient.
