Your stated objective is to retire in 2032 with 10 Bitcoin and 100 Ethereum. If I can get 1 or 2 BTC before that time, I'll be fine.

It is never necessary for someone to have a defined objective to amass 10 BTC and 100 Eth before retiring by 2032 because of the volatility of the cryptocurrency market. Depending on the quantity and value of Bitcoin in my portfolio, I can retire at any time. I can choose to retire happily if I should have 1-3 BTC before 2032 and the price of bitcoin increased more than I anticipated over the next bull run.

10BTC and 100ETH is a good starting point for a retirement fund. In my place, that is a very high price that, even at its current value, can provide you with a comfortable life. Looking ahead to 2032, when we all hope prices have risen further than they are now, it will be an excellent retirement plan. Although market volatility should be taken into account, you may not be able to exit the market at its ATH in 2032.

This looks to be fair amount for the retirement. In the past it looked like an easy investment based on its current price. Even after this we'll get more opportunities in the ten years time. We need to have perfect plans and start saving, so that we can buy the mentioned number of Bitcoin and ethereum at the best price. If not, atleast we should start DCA technique by now onwards which helps to accumulate the number at an average price.

over the last couple years i've told people hodl at least 0.1 BTC as long as you can - it may change your life one day.

hyperbitcoinization could send the price to $100m per coin (in today's buying power)

even if BTC has market share with XMR and possibly a few others, how much money do you need?

If you plan to retire in 10 years then it shouldn't stop your buying power, right? You should be buying a good amount of Bitcoin every year, let's say you are able to afford 0.1 BTC per year from your salary or business, in 10 years time that's 1 BTC, how incredible is that? Right now, 0.1BTC is 2744$, this is very achievable every year for the working-class, if we have to break this amount further down, this is 228$ per month.

I believe this strategy is far more going to be effective, instead of buying 0.1 BTC like some recommend and sit on that for the next 10 years, not good enough to me, use the next 10 years to secretly accumulate Bitcoin 👍

Depends on where you live and where you are willing to live. Yeah, 10 BTC and 100 ETH at current price is actually good enough and you will be able to retire in some countries like situated in South America. You can own a house and a car, and lead a decent life. This is based on current price. If the price in next 10 years goes up more, you can literally own a mansions and lead a luxurious life in those countries. So yeah, you are doing the right thing saving bitcoins now.

But like you said, no one can exactly predict what the price is going to be in next 10 years. Chances are that the price is going to be higher, but there is also a chance that the price will be much lower than it is today.

Don't think about how many bitcoins you need. You can never get enough BTC 

So I think it's best for you to just keep accumulating and not think about it. Eventually, you will realize that you have enough.

What exactly do you mean by retirement? Do you mean I should sell all of my bitcoins after holding them for ten years? I think this is arbitrary; 100 bitcoins may be sufficient for you, but trust me when I tell it is average money to another person, and why would you retire from Bitcoin in 10 years? Is owning a bitcoin for life and selling it whenever you feel like it now a profession from which one must retire? That's something I'm not sure about.

Have you also had the thought of it crashing back to your initial investments or the price that you bought? "What if" you bought the bitcoin at an average price of $30,000 and then in the next 5 years and the price surged to $300k and then another 5 years it came down again due to unforeseen circumstances like we did have so many instances of exchange insolvencies and Luna moments, how do you retire from this kind of situations? These are the things you should consider when you talk about retirement.

Thta is simply not true at this moment and this bear market is the best reason why. If OP retires and in this moment the bear market is going on, then he will need to wait for a few years until he can sell his bitcoins for profit. How can he however live in those years? If he sells in bear market he will have a loss and will not have enough bitcoin to retire. If the does not sell he needs to work again. Also OP can get sick at some point where the prices are low. How can he get his money then.
In General you should have more then one asset class. It is easy as that.
