Buy and holding 80% of what I make while investing 20% in researched market moves seems like the best idea and what is making me have the most profits. I take a conservative approach because I was sure that sooner or later price would go up, so holding most of it would be the most efficient way to raise my wealth.
Actually, I really like your approximately 80% holding BTC 20% trading allocation, yet at the same time, I think that it would also be a good plan for you to consider how those BTC/trading allocations may be somewhat flexible based upon different projected BTC price points.
Maybe in the end, you will come back to the belief that 80%/20% works best for you at all projected price points, but it would be a good exercise to consider ways that you might trade more under certain scenarios or keep more in fiat under certain conditions?
Personally, I consider my trading portion of my BTC holdings, as not really a gambling portion of my BTC holdings, but moreso as a portion of my BTC holdings that are largely in fiat and somewhat fluctuating and authorized by me to fluctuate between fiat and BTC depending on BTC price moves.. but largely that "trading" portion is in fiat and there is some fluctuation in that portion depending on the speed, intensity and duration of BTC price movements in either direction.
Furthermore, I also work that in a relatively conservative manner, which tends to pay off pretty well because BTC prices tend to overshoot on a regular basis and to reverse directions at unexpected times. I really think that no one can really predict short term directions, except for maybe some whales, and probably they even get surprised when they cannot sufficiently manipulate the price direction to the extent that they would prefer.
