Recommendation: do not invest in cryptocurrencies for nothing

Ackerman, chief financial officer of the United States, said he would not invest in cryptocurrencies for free. He thinks cryptocurrencies are good, attractive technologies, but he won't spend money on cryptocurrencies that aren't important. If you are spending a lot of money on cryptocurrency, you may feel frustrated, and if your friend hears that you are spending a lot of money on cryptocurrency, I would suggest a difference in your investment.
