Some people are saying BTC will be $1 million per coin in the future. But when that will happen I really don't know.
The answer to your question is here:
if bitcoin had a marketcap of $1Trillion, 1 bitcoin would be worth $58,551.69. I believe $1 trillion is easily achievable in 2-3 years. When / if everybody jumps on board, the possibilities are endless. My OWN personal prediction is, it will collapse in 10 - 15 years time. IF bitcoin is still dominant in 10 years time, $5 trillion marketcap out the question? im betting on $200,000 - $300,000 ATH.
just like @crypto brother said
Experts also predict that with these achievements, Bitcoin has the potential to record a much higher value next year.
If bitcoin has a great demand the price will be very high
