1. Starting today on April 10, 2021 if I invested 150k in bitcoin, how much do the gurus expect me to have in 1, 2, 5, and 10 years? Like would any idiot who just invested today and didn't sell expect a 5x increase within the next 10 years?
Nobody knows exact returns and Bitcoin like everything else have cycles in uptrend and down trend, but with current money printing and inflation I am expecting everything to speed up including cycles.
Best time to invest in Bitcoin would be in downtrend or dollar cost averaging, but my amateur prediction for next 5 years is that Bitcoin could go to $400k but with huge volatility.
2. I would use dollar cost averaging, but over what time horizon? Invest 150k over the next six months? Or just invest it all today since we all know it's going up?
Dollar cost averaging is much safer and proven strategy and going all in is much more risky so you need to decide what you want more safety or risk.
3. I could withdraw the old retirement fund and get the initial investment up to 300k. Would you go all in using that? I would not have much of a backup plan for retirement if this is the case, but like I said I have a high risk profile. I do believe this is once in a lifetime.
I would never do that, I would never sell a house or borrow money from other people just to buy Bitcoin or do anything crazy like that.
This is pure gamble and few years ago it would pay off much more than now.
4. If I want to pursue some alt coins, and again, I have a high risk profile, what % mix would you recommend? 33% alt-coins and 66% bitcoin, or 50-50, etc?
I would not buy and hold any altcoins now especially that new shit coming out every day, but if you really want it I would keep Bitcoin at 90% and play with rest 10%
