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.
I want to believe that before you could have all your crypto assets on the alt coins, you must have been invested in the few potential coins because it is really a tough road for Investors especially those who had not tested the water on the decentralized finances.
And being successful in the alt market is like winning a jackpot because due to it developers hyping and the volume of volatility extremely high making it ambiguous for investors to dictate the alt coins market events unlike how we can tell when we are in the bear of bull Bitcoin market and as well knows about the series of events in the 4 years cycles.
However, you may not need sell all of your alt coins just to invest on Bitcoin but rather, you can sell some for diversification while your major assets holding be on Bitcoin.
Reason being is the potential risk of having all your eggs in one basket in the moment of short term or emergency needs and perhaps, during the alt seasons, you might be making some good profits while you propagate your massive returns on investment (ROI) in Bitcoin
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?
The future market price will always remain unpredictable and if we can not predict the value of ros current bull-run will peak at it ATH, it is not 4 to 5 years ahead we can be sure of.
So I will urge you don't hope to know what the next round of market event in the interval of 4 years ahead would be before you can invest.
