I think Elon Musk don't support bitcoin, the Bitcoin cryptocurrency will continue at its own pace. In particular, if a bucket of water is added to a sea of water or if a bucket of water is lifted, there will be no change in the size or volume of the water. Elon Musk will not be able to change the state of Bitcoin by trading Bitcoin in his companies. However, as a rich man, many support him.
So the old merchants, according to him, increased their investment and trade on coins, albeit a little. But I think cryptocurrency does not depend on any one race or group. Cryptocurrency has been running at its own pace from the beginning and will continue to do so in the future.
