if you bought bitcoins at 2009 may be you are millionaire now.but due to some reasons 2013 bts price was going down.lot of them are sold their btcs.sorry for them.
japan gives permission as officially papyment as bitcoin.but i do not think japan is the leader in the bitcoin.beacause china has bigger mining projects.so china is the most probably a leader in the field
for a clever hacker everything in online is nothing for him.if someone gave accidently his private key,there is nothing to do. private keys are a random number in an unbelievably huge range, so it is hard to guess praivate keys
still it is not clear to me.maybe because of affraid of virtual currency.what happened if country people lose their crypto money.tax is another way to banned bitcoin.they cannot put taxes to virtual ones.
I do not know any stores that use bitcoins in my country.so i do not have any experience in using btc for trades.i think HODLing is better than trades.
We can give our physical property but what about virtual thing.will they be satisfied So you have to make hardware wallet like pendrive and give it to him
I agree ln that. However if your email is scured and your password is unique, there no chance for hackers to hack your bitcoin wallet since it's fully encrypted for them to prevent hacking.and don't give your private key to unkonows.
After bitcoins are all mined (reaches it max supply), miners will not get reward from generating new coins, but they will get transaction fees. Bitcoin will not fall apart, it will continue to grow on transactions and volume.
