Digital currencies are for speculation only, not for storage

Dear investor...the field of digital currencies is one of the worst areas of investment because it is based on speculation
Cryptocurrencies have zero real value
It has no tangible magical value and its value is derived from the fact that another person wants to buy it at a higher price. If a time comes and all the people decide that they do not want to buy the digital currency, they will find its price touching zero, and this happens a lot with meme currencies.

Even Bitcoin, if a time comes and all countries issue a ban on Bitcoin trading, will find its price below $100 because it has no real value.

You can invest your money in gold, real estate, trade, or tangible material goods

Cryptocurrencies are only for speculation...
That is, do not invest $1,000 in Bitcoin and say next year I will earn $5,000.
If this actually happens, don't expect it to happen every time
Perhaps something new will be discovered and Bitcoin will fall very sharply, thus causing your wealth and savings to disappear
