Many people are talking about Bitcoin hitting $1 million USD in the future. Crypto enthusiasts are very optimistic, as they believe their dreams will come true with a Bitcoin halving taking place every 4 years. If Bitcoin hits such price levels, many early adopters will become millionaires. It could be tempting to either sell all of your Bitcoin or "hodl" it for the long term.
What will you do if Bitcoin hits $1m in the future? Will you sell all of your Bitcoin for cash? Or will you go long in the hopes of Bitcoin reaching higher prices on the market? Will you donate your profits to a charity? Just curious to know. Your input will be greatly appreciated. Thanks.

That's very strange question. Why should anyone disclose in public what he is going to do with his money.
One thing I can assure you is I am not going to convert all my holdings to fiat. What is the purpose of supporting crypto if you sell it for fiat.
I hope by then everyone will start accepting btc and I won't need to convert it to fiat to pay my bills and other expenses.
