A site that gives +5 luck for an investor

Most best way Don’t repeat the mistake - come up with a rule that will allow you to remember the very same rake that you stepped on.

How I became a plus, but went into a minus

Without further explanation, a paragraph heading is an example of mutually exclusive paragraphs. So let me clarify: one of the projects where I invested funds paid all the interest and the deposit amount. But due to cryptocurrency prices, I ended up losing more than I won.

We are talking about Der Global - at the time of writing, a quite paying and working project, which has not yet gone into scam. In mid-December, I selected it among the most promising ones and decided to invest there the free ether that was hanging around idle in my wallet. This project transfers all investments into USD - I did not pay due attention to this factor then. As it turned out, in vain.

I invested $500 worth of ether, a deposit for 20 days, with an accrual of 2.1% per day. Interest payments are made daily, the deposit amount is paid at the end of the deposit period. Everything went smoothly, and I received my $709.5 at the end - the project paid out every penny, also in ETH.

Only in these 20 days the ETH rate has almost doubled, so my initial investments in crypto, if I had just left them lying around, would have been worth not $500 but $900.

Conclusion 1: you need to carefully study all investment conditions

When evaluating a project, pay attention to such little things. Often the answer to the question “will I have time to withdraw money from the project before the scam?” overshadows everything else. The project is a scam - far from it the only one risk. Eat unforeseen risks that are impossible to predict, because such things simply have never happened. And there are risks unforeseen- those that we overlooked, although we could have taken them into account.

Conclusion 2: you need to look at the bigger picture, assess the situation as a whole

What currency will you invest? Which payment system will you use it? Where will you withdraw funds? What are the forecasts for the exchange rates of the invested currency? Answers can be found to all these questions, which means they need to be found and these risks taken into account. We cannot protect ourselves from a black swan—an unforeseen risk. But from inattention and a narrow view - completely.
