bitcoin is number 1 in "store in value", as you can see, bitcoin price is the highest among crypto-currency. not just because bitcoin is the only one original crypto currency but bitcoin is the very most popular and indemand all over the globe, although bitcoin has many issue like for example transaction speed, a very slow transaction confirmation in blockchain, bitcoin still the no.1 in terms of store in value. and I think it will be more price hike coming for the year 2018.
