Currently, I do not own any Bitcoin but my plan is to sell all my altcoins later this year for (hopefully) decent profit and then buy Bitcoin only starting next year once it has crashed from the expected highs that we see later this year.
It's not a bad idea to sell altcoins to buy Bitcoin because the former is less reliable and risky. You should also know the right time to dispose of these coins since the price can drop very fast. You might end up not making much profit if the value of these altcoins drops.
I am assuming 2029/30 will be a peak high as that would be the next bull run if the 4 year cycle was to continue.
What price do we think it can be then? I am expecting it to be at least $400k and if that happens I plan to sell all the Bitcoin I manage to acquire and pay off a big chunk of my mortgage (I bought my first house 18 months ago and want to pay it off asap).
Bitcoin has a certain four-year circle which includes the halving and bull run. We have not gotten the ATH for this season, hence it will be difficult to predict how the next bull run will be. $300k is my own prediction.
