Yearly rate is not convincing for me because 365 days is very long for crypto currency world. Even if I have utmost confidence about the projects long term success I wouldn't park for a year. I might miss big rallies even though I'm not a short term trader. There will be big opportunities in exchanges.
I hope they consider to add a monthly parking rate
They will. But later. I think after somekind time after reaching planned amount in 20$ per coin
