Did Bitcoin get any support from governments when Stock markets plummeted lately? No, because Bitcoin is seen as the enemy.
Still many people are more comfortable investing in government controlled investments because government controlled investments offer long term investment and if there is something wrong that happened the government will be liable for it, unlike cryptocurrency that offers short term investments and there are still other countries that are not yet accepting cryptocurrency. If cryptocurrency will last for more years I think many people would trust it anf more people will have the courage to invest their money in the cryptocurrency.
