I think we already had a low for this year around $7500. I expect to high to be at least $25,000 by the end of the year because of the halving.
This is actually no accurate timeline to expect, and as far as high and low price fluctuations is our main concern here I'd rather expect lesser than $25k this year. End of the year halving was too far to wait, and I do hope as it coincides with other people's predictions that early months of this year halving starts to create a bigger impact on the market demand which helps the price increase positively.
Too much expectations of the Bitcoin halving this year might hurt their feelings if what they expect won't happen right away. I would expect another breaking of the $14k to $16k this year since last year Bitcoin is having a hard time to break those price. Luckily, we didn't see a $3.5k bottom this year again so maybe the bottom will be around at $5k to $6k.
