1. INCOGNITO. this is the main reason why people use it. You cannot trace crypto transaction and its perfect from hiding.
2. CONVINIENCE. people nowadays are so lazy that they want to have transaction while seated comfortably on their home. With just one click , crypto can be transferred as payment to whatever they want. Well, who doesnt want that anyway.
3. TREND. basically, people want to try something new, something not ordinary , something innovative and if it was used by all their friends, they want to use it also.
4. ILLEGAL. yes, i dont want to include this but i saw many topics about this also. If you want to buy on black market or an illegal item, your transaction should not be traced as i said on our first reason so Crypto will help you hide on cops but not forever.
5. MODE OF PAYMENT. this is where some people buy an item usually using the profit they had on investing bitcoin even just holding. Ex. If you have 1btc and after a month it becomes 1.5 btc and you want to buy an item that cost 0.005btc and crypto is accepted as a mode of payment, you will use it ofcourse rather than fiat.
6. TECHY. it seems that techy people using cryptocurrency as a mode of payment see themselves as going with the flow of technology considering that bitcoin is the new technology of currency for the new generation.
7. SHOW OFF. whether we admit it or not, some people use cryptocurrency just to make their status up. Telling their friends about how wealthy they are and keep boasting for their ego.
This is what i noticed. So which one are you?
