Bitcoin 20K in 2021 - look into the past to see the future

Current price scenario looks for me similar to beginning of 2015. We have seen a nice and healthy rebounce from 3100 $ area. Now is the price searching for a top for the next weeks. I expect accumulation area between 3000 and 4500 $, this accumulation could take up to 12 months before a breakout from this channel is possible. Another year to reach 20k.
