Turbulence in the conventional currency market sent Bitcoin soaring by 10 percent in mid-June, according to Gallippi.
After the Greek government implemented capital controls to prevent bank runs, Gallippi said he expected Bitcoin prices to top $610 and go as high as $1,250 if Greece quits the single currency euro.
"The Bitcoin market just needs a little grease to get unstuck," he tweeted.
The price of the cryptocurrency has been climbing steadily ahead of the June 30 deadline for the Greek debt repayment. As of Monday, it had been trading at $255.
Bitcoin saw a similar surge following the banking crisis in Cyprus two years ago when its price jumped tenfold to top $1,000 before crashing.
Bitcoin is a digital currency that can be used like any other currency to purchase goods and services from stores and online retailers. Its independence from central banks and governments sets it apart from conventional currencies.
