You are here, so you are very lucky (as are we).
You just need to shift your mindset to a minimum of five years.
But until now I am doing good and also will invest more when have the money.
You’d be stupid to sell anything at all until 6-12 months after the halving which is still 8-9 months away.

Anyway I got your point might be need some strategical time regarding the halving period.
I generally agree with LFC, but I do wonder about the range of 6-12 months after the halvening.
A person would be less stupid if at least waiting until 6 months after the halvening, but even less than that if waiting until 12 months after the halvening?
I am thinking that LFC is saying that the larger of the exponential price periods of bitcoin's growth is likely to come somewhat after the halvening, because there tends to be a bit of a denial of the actual effect of the shrinking of the supply of the new bitcoins coming out of the printing presses of the miners. Anyhow, that peak is not exactly known, but we are going to have better chances of experiencing such peak within the 6-12 month window period than anytime before that.
Even though I agree quite a bit with LFC's hypothesis, I do have some trouble with attempting to bank too much on any such fractal comparisons, which is largely an attempt to compare what had happened in the last two post halvening exponential growth periods and to extrapolate what is likely to happen in this post halvening period. Even though I believe that there is a quite a bit of actual physical and material pressures on BTC.. which is upwards pressures on price due to actual restriction of BTC supply, I still have some difficulties putting too many of my eggs in such a basket, so in that regard, I do get some sense that if there is kind of outrageous exponential price rise that comes before that 6-12 month post-halvening period, then that outrageous exponential price rise could (but not necessarily will) take away some of the fuel on the actual restriction of the supply period, because in that case, if BTC's price rise had been front run in such an outrageous way, then there would not likely be enough steam to fuel another exponential price rise that happens in the 6-12 month post-halvening period that comes from actual fundamentals regarding the actual lessening of the new BTC supply.
Well, you gotta do whatever seems to work best for you. One of the things that concerns me, sometimes, is if guys sell too much too soon because they expect the price to go down, and if the price does not go down, then they are stuck with a bunch of fiat that really is not going to do them any good. So, as long as you are prepared for up and you have enough BTC, even if the BTC prices overshoot your expectations to the upside, you still have enough that you are able to sell a little bit at the higher prices to take some profits at those prices rather than these prices, which could be 10x or even 30x higher than currently.
Some dislike JJG long discours, but mostly he is saying interesting things. And just as everyone of us he also sometimes has a grumpy day... .
