finally one of the developers contacted me and solved the problem with my wallet by sending me the 3800 ARO that I had blocked due to a problem with my private key. These actions demonstrate the seriousness of the workers in this project.
Yes the Arionum team is one of the few teams with big actions and less words. Sometimes on bitcointalk u cant see it because they only place here some wallet releases. But on discord u can find out how much they are doing at the moment.
This can also be because they want to have a great product before they start the marketing. Many other coin teams got a great marketing but 0 actions. I don't take this coins serious after the years i am active in this world.. I prefer a coin like Arionum what are doing great stuff.
At this moment i am testing the Windows GPU miner what gives great results, there is still one bug (just reported, i guess also this one will be fixed today by a Arionum community dev..), miner close in like 1 minute after getting the error: Connection error to aro.cool (or whatever the pool i am using).
When this bug is fixed i guess the miner will also released on bitcointalk. Only thing what is needed after are optimisations.
