What about investing in Bitcoin through digital media?
How do you invest in Bitcoin through digital media? Are you talking about social networks?
Is it worth getting a loan to deposit to bitcoin?
Taking out a loan to invest, which is called investing or buying "on margin" is super risky. It's a very bad idea to invest in something as volatile as Bitcoin using something as finite as a loan. Don't do it. You're going to go broke.
What Are The Advantages Of Bitcoin?
(1) There may be a way to make money you have a high chance of losing money at the same time, so you need to know how the system works.
(2) You can only purchase certain products and services using Bitcoin.
These two things aren't advantages of bitcoin.
(1) Bitcoin is just money, you can earn it doing anything in the world you can do to earn money...you just need to ask or require you get paid in bitcoin. And having "a high chance of losing money" is never an advantage.
(2) Only being able to you use it to buy "certain products and services" is a disadvantage...you'd want to be able to buy ALL products and services, no?
