If Bitcoin goes from $64k to $256k, it means BTC will be worth 400% of its current value, and the gain itself will be 300%, not 200%. So, if you invest $1k today, you'll make a $3k profit. Is it achievable? In my opinion, yes. I don't know about other price predictions people are talking about, such as $1 million or $2 million, but I think something around $256k is quite possible, considering that Bitcoin adoption could easily increase tenfold from today's 400 million users.
I feel like $256k is still a pretty more grounded long term target than throwing out figures like $1 million or $2 million without being able to explain why they’re making such assumptions.
Although It’s still speculative, but still it doesn’t require an unrealistic leap if Bitcoin continues to gain adoption and demand over time.
Unfortunately, the market doesn’t have to agree with anybody’s prediction on any particular timeline. And even if Bitcoin is gonna eventually reach $256k, it’s gonna take much longer time than many investors would have expected, and there could also be severe drawdowns along the way as well.
