Is there a way to find out how much I have invested now?
think i had some 30 or 40 sahres only or even less

Yeah, send me an email at
deprivedltcasset@hotmail.co.uk (it MUST be from the email address you used for your BTC-TC account) and tell me which you held shares in (Mining/Selling/Purchase) - and I'll look up how how many you had and reply telling you.
Will be making a more substantive post here in a few hours - just going to finish off replying to all PMs/emails first.
