If you want to grow your capital, you have to learn about your investment options. Just putting it in a savings account at 0,05% is not going to bring you any closer to your goal of financial freedom.
One major key to success in investing is to start early. That's the only way you can put compound interest to work, and with interest, you can read dividend returns as well. Reinvest those, and your total return at the end will be huge!
For all legal and tax details you should probably seek professional advice, but keep a close look at costs. Never choose an investment where the advice is 'free' because what you don't see is that this advisor is likely getting a kickback fee from the product he has suggested you should invest in.
Don't invest in actively managed funds, because research has shown that those funds have huge expenses but not so excellent returns. Instead, look for a low-cost ETF. This is a passive fund exactly following an underlying set of stocks, bonds, etc. No active trading (which is costly), no expensive fund managers, or golf clinics with all their CEO colleagues.
Investing in real estate and actually owning it always seems a good deal. Over time you can increase the rent, and hopefully, the value of the property goes up as well.
All investments have risk, there's no other way. Always make sure you can handle the risk and still sleep well. Also, make sure that all risks of all your investments are of a different type so they don't get exposed all at the same time. Diversify in the type of risk.
