The currency $BTC is still the main engine and leader of market movement, as almost all currencies follow its movements up and down. Any slight movement that occurs to it leads to market tremors and changes in currency prices. Therefore, I always advise, before any movement whether investment or speculation, to monitor it along with the currency intended for investment or speculation. The real indicator of market direction, in my opinion, is the movement of currency $BTC . We may find some currencies that may rebel, even for a short period, against its leadership, moving in the opposite direction. However, this rebellion is temporary, and these currencies will soon return to follow its movement unmistakably. Therefore, I recommend following $BTC as a call for reflection.
