I am not sure exactly my strategy if we were to have another 10x bubble in the near future because that kind of price movement, depending on whether it occurs quickly, would cause a lot of temptation to sell a lot of bitcoins; however, even with a 10x increase in the price, a person would not need to sell all of his/her bitcoins in order to take reasonable measures to protect the investment.
For example, if a person has about 100BTC, then he knows that every dollar BTC goes up, he has $100 profits. Therefore, he could sell some of those profits and maintain the principle... There are probably as many strategies as there are people; however, I am mostly similar to you in the sense that I am attempting to accumulate overall (even though at the moment, your average BTC buy price seems to be a whole hell-a-va lot lower than mine)
When I first bought bitcoins (starting at $68) I figured I'd sell enough to recoup my original investment when the price had tripled in value.
By the peak of the spring 2013 bubble, my average price had risen to about $120 and the market price only reached $266, a hundred bucks shy. When the "dead cat" bounce took the price back up to $155 after the crash down to $50, I sold some coins and was feeling fairly smug after making a 30% profit after a crash.
It didn't take long to realize I wanted to buy more bitcoins though. Luckily I was able to buy back in for $97. Now I realize that If I sold any coins, I'd only end up buying them back again, probably at a higher price.
I happened to get lucky with my timing then but I can't count on being that lucky again. I'm not a gambler by nature (in fact I'm adamantly anti-gambling for myself) so I'll stick to the slow and safe.
Your method of accumulating and mostly holding BTC sounds totally reasonable and likely fitting for your diversification, risk tolerance, view of bitcoin, timeline and other factors that may be relevant to you (and maybe even only known by you).
Surely, there are likely a large number of BTC strategies that are going to be fitting to people, and some will be more profitable than others, others will be safer, others will be more diversification oriented and some will be more time-consuming.
Between November 2013 and September 2015, I only bought / accumulated BTC. I did not sell any BTC during that period, and any BTC that i did sell for transactions during that time was replaced.
Surely, each of us has various things going on in our lives and we do not necessarily feel that it is a good use of time to create complicated trading strategies in respects to bitcoin or any other crypto.. but some people possibly love that kind of activity.
By the way, I've never really gotten too much into any cryptos other than bitcoin, so my relevant trading experience only regards bitcoin.
In about August and September 2015, I began to tweak some of my longer term BTC plans (speculating various kinds of potential BTC price rises, including considering the possibility of another 10x bubble taking place within the coming years).
My mid-2015 tweakings and plannings around BTC got me more and more inclined towards projecting out various scenarios to both continue to accumulate BTC and to strategically cash out portions of my BTC holdings at various price points.
In October 2015, I put plans to practice, yet in my thinking, my plans and strategies are not really gambling because they are somewhat price agnostic while assuming a long term BTC price increases.
Surely, any snapshot of any BTC trading strategy will in part depend upon previous positions taken... Below is more or less my current BTC/Fiat trading position (assuming that my total BTC trading portfolio ($43,000 for example) were about 100BTC (96.37%) and about $1,600 cash (3.63%) )
