The question is not if btc will be 200 k usd each but are you going to hodl it and have any meaningful amount of coins when it happens. The answer is probably no. A lot of people will sell on the way to 10 k and they have very little coins compared now when we will have next halving day.
There's a lot of truth in this. Most of us get tempted when relatively high amount of profit are available, that we miss out on the bigger picture.
Exactly that happened to me few times already, but i think people will get smarter now, especially if this year confirms that price follows halving as a rule.
In any case, 200k is still very far from now, but it certainly isnt something that cant be done.
To be honest, even I will have temptation to sell when I see my coins are worth of 1 000 000 usd all together because that would be my first million dollars despite I am already 30 yrs. old. I have been a little bit too late I guess.
However, my plan is not to sell when the stack hits 1 million. Sure I want to cash out 1 million but I will waite a bit longer so that the stack is worth more than 1 million, then I cash out 1 million and leave the rest of coins in the wallet. Those coins I do not care anymore - I am satisfied with 1 million usd + some bitcoins - even 1-2 btc is enough.
You never realized that before
