Someone should ask these people that how and on what basis they are giving such statements . Bitcoin has been called a bubble more times it has been called a currency and that is just pathetic . Bitcoin is in its most stable point right now and there has not been a single sudden up or down in days now . When bitcoin was rising at a speed faster than a rocked it was feared that bitcoin might crash at that speed . But nothing like that happened and bitcoin became comparatively stable instead at around $14000 - $15000 .
Reaching at the level of as low as $2000 seems too funny for me at the moment witnessing the popularity and the green market of all other crypto currencies . 2018 will definitely turn out to be a relatively progressive and stable year for the crypto currencies and bitcoin will reach upto its highest levels by the end of 2018 .
