Just had a nasty though. Don't tell the tax office about this. They'll could tax you as income on the "New Coin" a.k.a. Ethereum you got for free, and you claim a capital loss on the drop in price of the old coin (Etherium Price - Classic Price). Yikes!

This may sound radical & all, but I think people may be investing in coins based on things which are other than 'rational'.

'I can calculate the movement of stars, but not the madness of men'.

If more professional investors get involved, that would likely change some.
