Guys i am just wondering what are the risks of investing to Bitcoin and other cryptocurrency to possible intrusion to the system?. Is this system secured enough for investments? Newbie here...
For the most part, the only security issues that I've heard of come from exchanges or services that allow you to buy bitcoin, not the actual coin technology itself. This is pretty amazing considering when bitcoin was created. However, I believe it's pretty important to keep the dangers of using exchanges in mind as well, especially when certain exchanges like Bittrex ghosted people's accounts and such.
Other cryptocurrencies can be built on other technologies, which really could be problematic. I don't generally think anyone would make a coin unless they had the intention of scamming in mind, so if you're investing into a large coin, you should be fine.
