I think it should be about 20.000 usd in near future
That's part which people are missing out on. It costs money to produce BTC and with rising difficulty, it costs more in newer hardware and so on. Miners are not going to unload at a price cheaper than what it costs to produce and this will result in rising prices over longer time periods.
The rise we saw from 10k to 20k in a short time is totally based on media circus which resulted in millions of newbies tossing in their money along with corporate money. That's all over so the price will rise back over $20k only if there is some major news otherwise it will linger around the 10-15k range for many months at least.
