With the passage of time, perhaps after mid-2017, I became more confortable with my maintenance status and my assessement that I had enough or more than enough bitcoin.
I had initially assessed that I had enough bitcoin by late 2014, when I had gotten my bitcoin holdings to about 10% of the size of my total quasi-liquid investment portfolio. Yet it seems that during 2015, I had largely increased the total of my bitcoin holdings by about 35%, yet I still was lacking some confidence in regards to whether I had enough bitcoin, and I suppose the bitocin price going up from in the $500s in early to mid 2016 and into the $2k to $3k arena in mid-2017 helped me to determine that I had enough and/or more than enough.
When your finance becomes better and you are like financial free, you can make your investment more effortlessly.
Your belief in Bitcoin and your confidence on success of your Bitcoin investment are necessary but later, your financial status and investment capital availability will make your investment stressful, less stressful or effortlessly as said.
To say feeling like "I have enough bitcoin" is so narrative and I believe that a Bitcoin investor will want to accumulate more bitcoin with time. It's challenging task because with Bitcoin adoption and price growth, with same capital you will be able to purchase less bitcoin over time, but accumulating more is not bad with this magic investment asset.
