disadvantage of having it
*The high volatility attach to it can be very risky.
* It's not generally accepted by all.
* It can be stolen if your system is hacked.
* It's almost near impossible to retrieve if sent to the wrong address.
Argument to disadvantage 2: It's not really a disadvantage because that's what makes it sought after because it's prohibited sometimes. The best analogy I can think of is drugs, the more we restrict the supply the more the demand will pay for a higher price.
Argument to disadvantage 3: It's not the fault of bitcoin, it's a me problem. If you're careless about your security, you're likely to be vulnerable to attacks.
Argument to disadvantage 4: Near impossible isn't the word and even with that word, that means that you can still get it back unless it's sent to a burn address which is impossible.
* It can make you filthy rich during the bull run.
* It decentralized, no third party like banks and financial institution.
* It's a self custodian asset, the privacy is priceless.
* It's very accessible at any given point in time.
I don't know if I missed some that I didn't mention.
Clarification to advantage 3: It's pseudonymous, not that anonymous as many like to think. But still it's enough to keep your privacy.
Clarification to advantage 4: In a technology oriented world it is definitely but in a desert or a mountain with no electricity, not really.
