Short about crypto currencies
Hi. I guess you all know what is crypto-currencies (it also called as "blockchain"). If no, crypto-currencies are virtual currencies. Pluses of blockchain: Yes, blockchain is good, but still it has minuses, a lot of them: They are only main pluses and minuses, i am not a expert, sorry :(
 * 1) Anonymity. For example, Ruslan Sokolovsky is declared as terrorist in Russia (inetersting fact - he just a vlogger, who disliked religion in his videos and catched pokemons on church to prove, that new "laws" about pokemon go in churchs are stupid and they dont work,but still thats why he could be in prison for 3 years, but he is just arrested, wtf), and he cant use Qiwi or PayPal, for example, and he should use crypto currencies.
 * 2) Every user have something like a "diary", where records all (not just all yours, but really all) transactions, so if you wanna gain cash illegaly it will be failed, because you need to register that in all "user diaries", which is imporsible
 * 3) General price of crypto currencies are rises, and as experts says, it will rise in these 20-30 years, so it will be areason of world's economy grow and will replace normal cash as new, more effective and progressive currencies
 * 1) Unstability: yes, crypto-currencies are unstable, so its hard to predict, will price rise or fall. Noone exepted rise of Ethereum in last months, for example.
 * 2) Easy to hack: i will just give you one example - one day one of the biggest bitcoin exchanges were hacked and hackers got almost billion USD (450k bitcoins if we will count current price of bitcoin)!
 * 3) Some of crypto currencies can be financial pyramids, so its can be pretty dangerous for you

Mining
Maybe you will be interested: "how to get these bitcoins?". Right answer: mining. How to mine Bitcoins or Ethereum? You need videocard (GTX 480 for example). Thats all.

For example, in CIS countries (I am talking about Russia and Ukraine, i dont know what happends in other countries) almost all store shelves where video cards are situated are empty, because miners bought everything.

Some videocard producers decided to make special video cards for mining. So, if you wanna to have cash - buy videocards!

Legalisation of blockchains
If you wanna use bitcoins, you should know where it is legal, where - illegal.

Blockchain illegal in Bangladesh, Bolivia, Equdor and in...right! Russia! Russia knows how to take an example from really "rich countries"...ok ok, no politics.

But blockchain legal in Japan, South Korea, Nordic countries and some other progressive countries. In China things are more complicated: you can use bitcoins if yur just a person, but cant if youre a corporation or company etc.

Conclusions
Blockchain is really a currency of future, which will change monies at all. If you like it or no - it will happends. I think it is only better, because it was made by ordinary resident for ordinary residents.
