The situation before is different than the situation today, before people are too naive believing every words these Bitcoin "prophet "said. But now people are more vigilant due to a major set-back happened last 2018 where many Bitcoin investors lost their capital value. But imagining the halving events, the supply, adoptions, start-ups and disregarding either FUD or hype, by mere supply and demand ideals, Bitcoin price will definitely go up. In a decade and three years (2032) time Bitcoin will be producing less than 1 BTC (0.78125 BTC to be exact) per reward and with larger demands on the audience, what would you think the price would be? I doubt we will stay in this range.
Its hard to say something about what will gonna happen in the future.
Rapid increase in price of bitcoin doesnt happen over night. It will take a lot of years to happen. More than 3-5 years, its price will change again. We will again see how bitcoin will make a history for itself.
That time I am sure legalization will happen from all over the world.
But the increase in price is inevitable, adoption will increase in multitude, supply will be cut into half every 4 years, there is no other path for Bitcoin but to go upward . The price might be unknown for now but I have a feeling that it is way more than what its current price.
