Is it better to save money in bank or invest it online, in real estate or maybe gold?
i think it is really good to invest not matter where, better than just keep them
and if you can, don't invest in gold or silver, but invest in bitcoins because their price will rise this year for sure so you can't lose, just win money
If you decide to invest, spread your investment. Categorize the possible investments you like into categories such as "no risk" / "very low risk", "low risk", "high risk", "very high risk". They decide what you want to spend in. Investing in Bitcoin might be a good idea indeed, but I won't invest everything into it. I would categorize BTC in the "high risk" category I guess..
Real estate might also be a good investment. Currently here in The Netherlands, I think there is a quite good possibility to step in investing real estate (house prices are rising and rising, probably also because of the cheap possibility to loan money).
