I've been called a faggot when BTC went above 2000$ and the person who got pissed knew I bought in at 4$
Wow, congratz. I actually had the opportunity to buy bitcoin at $100 like a lot of other people did as well. But we didn't take action.
The monetary supply of a currency in my opinion is one of the most important ways of determining whether or not it is worth it to hold it for the long term or not. Fiat currencies are known for notorious government intervention, and oftentimes the fiat currency ends up being worthless pieces of paper.
Gold and bitcoin are similar in the way that there is only a certain amount of bitcoin available to be mined. So even if the amount of demand for bitcoin only increases by 5% each year(impossible imo), priec is going to go up in the long term as demand outpaces the rate of inflation.
Long term holding is the safest strategy out there. The only way to profit in the short term as much as you do in the long term is to margin trade, and that isn't worth the risk in my opinion.
