I remember when Bitcoin was a $3,000 coin during a war, it dropped from $10k or $20k, I think.
I think you mean Bitcoin correction from $20,000 to $10,000 in 2018 from 2017 ATH, and from $10,000 it falls more to $6,000 that was considered as a solid bottom for entry, then no war but Covid-19 force Bitcoin to crash from $6,000 to about $3,000.
Last year, it dipped to $15k, we invested on that price and I'm one of those people so happy seeing it hit $90k. guys, Im telling you, its a banger investment of my life.
I experienced this market since 2017 and that means this cycle is my third one in Bitcoin market. The common mistake I saw people made is they wanted to wait for lower price, lower price and don't know what is their entry. Then they missed very good prices for entries, many times in bear market that lasts for about 2 years. Hence, when market bottomed out and started its rally, they regretted their mistake and hesitation to buy cheap bitcoin. They repeated it cycle by cycle and wasted many good chances.
From $15,000 to 2021 ATH, it's four-fold increase and ROI is very good, no reason to hesitate with $15,000 but I know many people were fearful and missed it.
