Can you guarantee good performance of my investment?
Absolutely not. While your investment may deliver high returns, it is more likely that you will lose money. Do not invest if you are dependent on the funds you invest.
How likely is it that I will lose money?
On each single investment, the likelihood of losing money is higher than making a profit. Given that the potential loss is limited to the money you invest while the potential upside is unlimited, a diversified portfolio of trickle-investments is advisable if you are seeking to pursue an investment strategy with good odds of being profitable.
