I can't find prove online where Elon Musk said that BTC is bad, are People just spreading FUD because this man is chilling coins they expected the least?
He did not say that as he is also an investor of Bitcoin, he never tells people about his participation and investment to keep his name safe from media and that is why he just tells that Tesla did this.
But I don't believe you never see or hear his announcement that Tesla doesn't accept Bitcoin anymore. Maybe we could ask how about those Bitcoins that the company had? Are they dumping it now that causes the sudden price fall? That something be right and can't blame people that they are talking bad towards Elon as he was the reason for this (in his tweet).
Most people I knew said why Doge coin of all coins but mind you this guy have already changed the lives of many this year, those who can't afford costly coins have make some good money through doge, I used to own two million pieces of doge coin myself just for fun sake, I never knew this day will come, the fact is crypto is a land of opportunities, just ride along and drop off at a certain destination and wait for the next ride another time.
If you think that Doge could save you and change your life, it was your choice, nobody stopping you. But I hope you won't regret it later.
