Like it! I would introduce the following small changes:
"Its Proof-of-Burn (or virtual mining) algorithm, that by the recent estimates provides up to 39% of yearly profit, grants to everybody the possibility to mine coins without any specific hardware and with a minimal computing power employed. It also contributes to a balanced power structure without an almighty elite and to a clean environment for future generations"
(the "hassle" part is imo not that important as it's more or less the same that the previous sentence, so one could use the space to refer to another advantage)
"The economic model that is behind Proof-of-Burn mechanism is not within the get-rich-fast trend, but rewards long-term involvement. So Slimcoin has a potential to shine should the traditional coins markets become saturated."
(to specifically include the phrase "long-term involvement", or, if you like it more "long-term investment")
Thank you very much for your comments! Let's wait another day to see whether someone else has anything to add and then I'll send it to Freiexchange with you corrections.
I'll try and have a look tonight and get back to you.
