Why HODL is the best strategy?

Let me tell you about my journey. I heard of bitcoin in 2013 via a computer nerd friend. he was so hyped about it and told me to buy just a 100$ worth of it. I was going to buy but it wasn't as easy as now back then to buy crypto had to transfer my hard earned money through some places and i lost the hype thinking about the fees.

He kept telling me how bitcoin is going and after like 2 months i was glad i didn't buy. it crashed from 200 bucks to 80. i was telling him to not spend too much money on it and its just like gambling.

After like 3 or 4 months BTC broke 1000$ and that is when i bought. People were telling "you will never gonna find btc below 1k, its your last chance!" i fomod in and bought 5 BTC at that price. not so long after that it crushed below 600 and i was panicking. asked my friens whats he doing. turns our he wasn't even checking the chart. told me to stay calm and hodl.

i was trying to stay calm. and try to imagine i lost that 2k gambling. i decided not to check the chart ever and do what my friend tells me from now on. His first instruction to me to buy BTC again at 300$ i did what he said. after a while our plan was just to buy BTC whenever it goes below 5k. and im glad we did that.

Still holding to this day.
