That would be 11.4 months to break even if prices stay as they are. Is this a lifetime contract and is the Gulden team involved ?
Yes, it's a lifetime contract.
And both yes and no, on the involvement of the Gulden team. The initial idea was mine, but Hybrid is a joined and worked out startup.
I merely execute the project, but the project itself if owned by it's participants (the shareholders)
OPT out and you get your btc back after earning all that NLG ?
Yes, that option is available. It is explained here: https://community.gulden.com/t/project-hybrid/1424/27
Any payouts in Guldens already received, are not taken into consideration into the equation.
