There is one big danger ahead. If the paper money gets removed, you will have no choice but to accept to get paid in crypto currencies. And to the big point:
If you keep your money in a goddamn computer, the government can rip you off instantly if they wanted it. I am not saying they aren't doing that already as most of us are keeping *our wealth in the banks. But cryptos will make their jobs easier. Much easier.
You are wrong on this one. Cryptocurrencies will make it harder for anyone to steal and get anybody's Bitcoins if they know how to secure them correctly. Why don't you try stealing the Bitcoins at Satoshi's wallet or ask your government to do so.
What if bitcoin price rises to 1.000.000$ and gold and USD become literally worthless? That's when bitcoin will be the world currency, and people gonna realise that gold is just a stone, USD is just a toilet paper.
Your won't have another choice but to store your money only in crypto, because the other choices will be worthless!
I am not sure if that's a good thing. Being dependent so much on computers just scares me.
What is your point here? We already are dependent on computers even if Bitcoin was not invented. Bitcoin is not even widely used yet for that to matter if you think deeply about the situation.
It is also impossible for gold or fiat to become worthless just because Bitcoin will rise to your impossible figure of $1m. They could possibly become worthless but not because of Bitcoin.
The point is, when bitcoin becomes the only choice for storing your wealth, you won't have anything physical to hide from someone (like the govs). They will be able to tax your money from the source whenever they like.
It may look unimportant to you and you can say "i have nothing to hide" but not every government out there are saints. Some of them are pretty evil. I am aware of that gold won't die so easily but it can lose so much value that it won't make sense to hold them anymore.
Look at silver, would you keep hundreds of silver blocks to protect yourself from the shady govs if you had to? Silver's worth is almost shit. It carries so little value compared to gold. Same can happen to gold... I wouldn't want that to happen tbh.
A little piece of gold can store thousands of dollars in value right now, it is that valuable. Buy gold and bury them into the ground and you are safe for all eternity. (until bitcoin destroys it at least
)
