Even though Bitcoin volumes across exchanges have been low lately, Bitcoin transactions on the blockchain have actually been increasing steadily since late March of this year. This means that interest in the asset is growing but the large buyers are not buying on the exchanges but instead buying OTC, thus not increasing the price. The graph shows that the blockchain has steadily seen more activity since it bottomed out earlier this year. Many analysts say that its just a matter of time before Bitcoin breakout but that time period could be anywhere from a week or two to a few months. But at a certain point when the transactions and buying overtakes the supply in the OTC market, it will have to spill over to the exchanges, but hopefully that comes soon.
