I would say we hit around 100k USD by the end of 2020, seems fair to me :-)
Might be fair to you and others but I'll taking my guess around 2021 onwards. We can take a guess or prediction but it's difficult to see if those predictions we've made are going to be accurate.
I want to see bitcoin hit $100k early by 2020 or after the halving but I don't want to expect with a high price for a very short time.
and my hope is that the price of bitcoin in 2020 can reach a very high value, and if the price forecast for bitcoin is very difficult to be accurate because the price always increases and decreases
Speculations plays a role in this market, bitcoin is speculative so those forecast might happen or it won't. Don't be too dependent to them, as long as you have a long term plan you should be good but think at what price you will start to sell.
Those speculations can be accurate but most of them are not. Everyone hopes for a good price of bitcoin, I've been seeing video now the 'end game' price for bitcoin and it's too much to think of while we haven't reached those high speculations.
