This is certain. The cryptocurrency can circumvent some laws. The cryptocurrency is also the new order of the world currency. It will change the relationship between the state and the state. In the future, no country may impose economic sanctions.
I myself use bitcoins and recommend peoples to use it. Other invested plat forms like Stock market, Gold and silver and totally useless. Thats my opinion.
Well opinions could be different because I think though Bitcoin is the latest and most economic way to make money, the rest of the platforms you just talked about have also been great spots for investment and people have made great fortunes in it.
Gold is still one of the most attracted and profitable way to make money besides investments in real estate and stock market. Economic theory says that no mater where you invest, you will make profit, now it is the scale of the profit that is affected by your intellect and business plan.
