Most people only invest what they can afford because it's really hard to go 100% unless you are used to risking your wealth throughout your life and you are making your investment like gambling. I think others always choose the safest one we have pointed out above and to buy bitcoins with the money you don't have any use for is the right thing to do because after all, bitcoins are still volatile and anything could happen in the crypto market that could lead to your great regret of neverending happiness if you hit the jackpot investing at the right time with huge capital.

DCA for buying bitcoin is better than just buying all of it in one lump sum for two reasons:

1) You may not have enough money to buy all the bitcoin at once, so this allows you to spread it out.
2) In case there is an emergency after Bitcoin price dips, you're not suddenly looking liquidating your bitcoin investment at a loss.

Although if you do have enough money for a lump sum purchase, then by all means, do it.

• Miss Alice is going to have a lot of work to do, keeping up to date with these random altcoins for their peaks and ensuring that they are still liquid over time. Otherwise, Miss Alice will probably lose that portion of he portfolio. Especially if they are not researched and completely random altcoins.
• Mr. Bob and Mr. Theymos will do just fine if they have a 4+ year time frame and they keep up to date with how the market moves. If they take profit when it is reasonable to do so, and either DCA/rebuy later down the track after the halving cycle has finished, maybe they will both do well with both strategies. It really depends on their discipline and emotion when it comes to selling/holding, not just about the strategy they used to buy.

Who is wiser? The one who holds and manages their capital, position and risk responsibly, and appropriately.

Here I would say Miss Alice will end up losing 50% if she goes for random Altcoins and I think both Mr. Bob & Mr. Theymos are would be making wise decision and I personally would go 100% with Bitcoin or else 70% with Bitcoin and remaining 30% which I can afford to lose hence I will be using these 30% into the Altcoins like SOL, ADA and INJ as Altcoins can give much higher profits during bull run (comes with higher risk).

Theymos is the clear winner here but only if the DCA makes sense. For example: if the starting funds (100%) are 10000 usd then obviously it will take Theymos 100 weeks to fully complete his DCA. That is way too long and by then, Bitcoin will probably have significantly risen in price. And while he made a profit from past DCAs, they won't amount to much.

A daily DCA in such a situation would make more sense.

Current market conditions are increasing, of course the price of bitcoin is rising as well as altcoins whose prices continue to rise, okay I will answer according to the knowledge I have.

What Mr. Bob is doing is actually good if he invests long term in BTC and of course the market will continue to rise because soon there will be a BTC halving and in 2025 there will be a bull run.

If Miss Alice buys 50% BTC and 50% Altcoin, that is also the right decision as long as you buy quality Altcoin, then of course you will get bigger profits because when the price of Altcoin goes up it always goes up very high, it can even be 500% during a bull run.

I think Mr. Theymos has done a good and wise thing, even when there is a price increase, the DCA system can indeed be applied and only buy when there is a price decrease, of course we always see that there is always a correction and it is during the correction that we take advantage of the opportunity.

I think in this case everyone has individual reasons and indeed the most appropriate and safest thing is to buy crypto during a bearish market and if you buy during a bull market it is of course very risky because crypto price movements are difficult to predict.

All three will certainly profit in the bull market but OP's question is, who is smarter and gets the most significant gains? The market fluctuates very unpredictably, so I think it is impossible to know who will achieve the highest profits. But if it were me, I would choose Miss Alice because altcoins will usually have better gains than bitcoin when a bull market appears. But what is more important is whether Ms. Alice will take profits on altcoins at the right time or will be greedy until she loses all profits because once the bull season ends, altcoins will plummet. Profit taking time is also an important factor that determines the profit of each investor.

My preference would be to go with Mr Bob, it’s not as exciting as Miss Alice & the potential profits will be less than if Miss Alice hits random lucky altcoin pumps but slow & steady wins the race. I prefer the more proven method.
DCA can be good but with the bull run nearing I think if’s too late to take advantage of DCA, smash buying would be better at this stage in the cycle.

Since you're talking about profit, the answer is no one can know who's wiser here.

Mr. Bob could make a lot money since he buy Bitcoin at once.

Miss Alice could make huge amount of money since she earn 3x-5x in Bitcoin and then 1,000,000x in Altcoins, who knows right? most people saying the 50% portfolio in altcoins will lose, how do you know which coin(s) she bought from 10K coins out there?

Mr. Theymos is unwiser because he want to ban mixer, sorry for OT.

This becomes a tricky question but I attempt from my own perspective.

In the case of Mr Bob who invested 100% into buying Bitcoin at one time can be seen if he had bought at the button dip, like when the price of Bitcoin was around $15k to $16k buying all at once would not have been a terrible idea but with the current price today if he buys now, there is every possibility of his profit to be or not bigger than the person who is DCAing.

Miss Alice using 50% to invest then 50% for Altcoin can be wise only if the Altcoin which she choose to invest gives her more than what she should have gained in Bitcoin by buying the DIP or doing DCA but if she takes loss then is she unwise.

Mr Theymos would buy at the current price, still buy lower and also higher due to volatility, there is every tendency of Mr Bob getting the higher profit, same with Mr Theymos.

But no one can tell what the future holds, as the person who makes the better profit becomes the wisest of them all.
