Bitcoin is always better than cash.For our bitcoin earnings,we are not accountable to government and we need not have to pay taxes unless it is legalized in the particular country.With bitcoin,we could easily send huge amounts of money with very low fee at high speed.With bitcoin,our money value increases,but with cash,our money just remains idle.
And even if you are traveling overseas then there is a limit to carry certain amount of cash and there is always a risk of loosing money or getting stolen or robbed but you can carry any amount of bitcoins in your bitcoin wallet and no one will come to know how higher amount of money you are carrying with you.
Yes and I find it a hassle to carry with me always those bulky wallets or noisy coins which is somewhat risky also. I hate how cash is passed down from different people all throughout the years it was made, I mean imagine how dirty it is just to be used again and again. Another thing is cash and coins can be easily forfeited or faked and even mass reproduction of counterfeit bills are a common scenario that happened in the past unlike bitcoin who is practically uncrackable and copied.
