It is a good idea to invest in bitcoin, the increasing price is better than other commodity and in the future it can become more valuable, and in the future I predicted there will not only 1 crypto that is valuable but some of the alt coin also become very valuable, so there is still so many potential to gain profit with crypto currencies, you just need to be smart in investing
yes that is really a good idea and specially in present time when the price of bitcoin is trading below 1000 USD, as still there are more chances that the price of bitcoin will start increasing very soon and hope that very soon it will recover its previous position.
