Recommending someone to invest in Bitcoin is some how risky. If the don't have the patience to wait for the bull season to commence the might sell at a loss and but the blame on the introducer. And many likes attributing their failures to someone then their success to their personal effort. I have learnt from past experience that before I recommend Bitcoin to a newbie I will first ask how long the can hold for and that will determine if I will be willing to proceed with guidance or end it there.
you are absolutely correct and the things you said are things I've experienced myself, I actually lost out completely on 2020/2021 bull run because some serious issues came up which required good amount of money to solve, I had no choice but to sell off most of my crypto holdings , and this happened just about 2 months before the bull run began, I could not make any money, I lost completely, I sold all my bitcoins and other cryptos at a loss just before the bull run, while the entire market was rallying up, I was just watching while counting my loses which was adding every seconds, this was one of my worst times in crypto, never in my life have I felt as bad as i felt those period..
And about recommending newbies to buy bitcoin, I must agree with you that its risky, its something one must apply wisdom when doing, else, you just gonna make a lot of enemies off friends you only intended to help.
