I just want to know how those people behind bitcoin secure the money they will invest because as far as I know there are lots of hackers all over the world.
The codes are automatically generated, therefore no one knew the unique codes created by the computer. But if we talk about the investment itself, investment has always the word risk on it, but as for the bitcoin there is no risk, because soon its value will rise again.
There is risk in bitcoin and there is no assurance that the value will rise again because the market is being driven by the law of demand and supply and if the demand will not go up and exceed the supply then the price will just continue to go down even further and that is why it is best to know the basics of trading so even though you are an investor then you will have insight about the things that can happen in the future based on technicalities.
