I use BTC for investment and trading, never used it as a medium of exchange or transaction. BTC is very profitable if you can manage it well. Known to many people, good performance and such a high value make Bitcoin more and more people's attention. BTC is very suitable to be used as an investment and trading because its value fluctuates, now it is precisely this nature that brings you profit. The fast and unpredictable ups and downs of the market determine your profit, you must expect the price to rise when you sell coins and dump when you buy it, the average person thinks like that too.
