You should have attached his tweet with your post to make it more interesting.
But that is needless to say although names of such has a huge impact with demand-based assets such as cryptocurrencies or Bitcoin to be more specific. Anyone can say the same thing but only few could really put weigh on such statement. As he have mentioned, Bitcoin will but don't expect for an instant increase. On its application, those who could wait should hold because there might be months more before we see a clear sign of recovery. But at the end of the day, elon musk does not carry the fate of this industry, things might change so you choose what to do.
Regardless of what is Elon tweet, its a certain fact that bitcoin will never stay dumping all the time but it will surely recover and reach significant heights in due time. Although we cant tell when its probably happening, but history has proven that bitcoin will never stop growing and increasing its value. So while bitcoin is still cheap at the moment, now is the perfect time to buy and hold more bitcoin and reap all the possible profits when the market turns bullish.
^We should not listen to Elon Musk anymore, this could be his test if his tweet has an effect on the BTC price, when it has resistance in the market it could mean, his tweet is very effective. Remember Elon Musk is a manipulator of the price not only on his shitcoin but also in BTC. But yes, that is definitely right, BTC price history has proven that BTC price will always increase in the end and those people who patiently wait and hold in a long term will probably receive a better reward in crypto. There is Elon Musk or without, BTC price will grow when the price goes up.
