Bitcoin can be unpredictable, but everything goes as expected, it might cross 50000 dollars also. If in some case it does not grow dont worry you will not loose your 20k, you will definitely get some profits.
Cryptocurrency is an absolutely undefined area.

There are a lot of events unknown to us that can completely erase all forecasts.

Events, as experience shows, are almost always extraordinary.

They can be either favorable or not favorable.

But no one waits for them... no one adds up ... but they will always appear... You can see everything now: hacking of exchanges, regulation, bans, forks...

Look at the weather forecasts for the week ... how often do they come true?

Although metrology is a science... There are many factors that they can not take into account, and therefore they do not come true often. It is enough to change the direction of the wind... and the weather forecast can be changed.

The market is a crowd of madmen. Especially the digital assets market.
