It's easy to make predictions in this voltile market as you can say the price can go over 15 grand or so, but making real judgments is very difficult or saying it's impossible because prices fluctuate very quickly depending on the current market environment. But if you asked for speculations, halving next year might have a positive effect on prices and push prices above 20k by the end of 2020 with normal corrections coming in between so just wait for the actual pump time.
The halving is this year not in 2021.
The price of a full adoption should be very high and the regular users should think in satoshis and not in bitcoins anymore.
Just look at hathaway berkshire shares. We could consider to reach as high as $200-300k until we're absorbed in the financial markets and, very important, tamed. That is then when the crypto market will behave as Gold, rather slow but stable. But with higher potential for the future, the new generation can't do anything with gold. We're living in a digital world now.
