their treating it like bitcoin is a company and your betting on the price. meaning your not actually buying bitcoin and neither is etoro on your behalf
you might aswell get ablank peice of paper and ask a friend to buy it of you and u just write down the details on a piece of paper.. this will not affect bitcoin prices as etoro are not buying from any exchange.
its all fake trading based on following actual trades on actual exchanges that are unrelated to etoro, this is why i think eft's and other crap are not worth it. its great for FIAT traders to make more FIAT. but those that truly understand bitcoin and want bitcoin to succeed. etoro has nothing to do with bitcoin.. its just a logo on their webpage and a chart that changes,, no actual bitcoins are traded on etoro.
its like their printing fakecoins
