I think in the time that the thought that has long seen the rating from 4 years ago until now is a very profitable appearance and bitcoin prospects the higher time to time but the traffic in each year there is a decrease of 100% to 50% at the beginning of the year to the middle the years of bitcoin traffic start rising up to 180 degrees and that's very profitable, now the profit is pretty big but looking at the bitcoin history is likely to experience a very drastic increase, and I remind again when many people who have bitcoin and just save and will result the bitcoin scarcity and the investor may switch to another coin, and I urge a bit of bitcoin to accelerate the bitcoin itself even though it increases slightly but will continue to rise so that the profits will be greater when the seller sells the bitcoin
