now because I am a little skeptic, but I can see that there is no decreasing value of the the BTC...
"you" should sell whatever amount of bitcoin you posses because you do not understand what bitcoin is. sell it now and try to come back when you studied a little and educated yourself about what bitcoin really is. try to think about what a decentralized currency really means.
i promise you that your skepticism will be over too.
the only downside to this is that by the time you understand what bitcoin is you will be forced to buy bitcoin at least $1000 above what it is currently worth.
