Please if you register via bitshares.gr and gifts are sent to you like bitusd, bts and you don't like the platform, at least cash them out, make them $ or btc or whatever or buy yourself something else. Don't just leave them there for no reason it is a shame.. Unless of course you want them for your children when 1 bts worths $1, but then please make sure that you don't forget your passwords as many bitcoin holders did in the early days
