Bitcoin is a volatile asset, so the value rises and falls according to demand and supply, investors speculations.While fiat currency is a government controlled currency used as a means of exchange.
All currencies both digital currencies and fiat are volatile in nature, you can only say that bitcoin is more volatile at the moment when compared to fiat and stable coins.
After acquiring Bitcoin, you will seek knowledge on which exchange platform to buy from, which wallet to use, the risks involved and maybe government regulations around crypto in your locality.
Things don't work like this, if you haven't known the exchange to buy from how then did you acquire the bitcoin because acquiring bitcoin means you have bought it already.
You buy when the market is bearish, hold for sometime and sell when the market is bullish
Wrong.
That's not how investment works, your logic sounds more like trading and you should know these are different concept. The proper way to invest in bitcoin is by DCAing.
Invest only what you can afford to lose
No sir, that sounds more like gambling and bitcoin has gotten to a level where you can't equate it to things like that. You can say that about shitcoins but bitcoin does not belong to that category of things.
