Camouflaged prices
Some cybercriminals use a scam already present in the world of finance to deceive users with fake offers of virtual currencies.
Beware of ICO scams
An ICO is an Initial Coin Offer. That is, an initial offer of a new currency. Thanks to crypto-currencies, in fact, anyone can issue their own currency. Except that in general a newly issued currency has no great value. However, if you were able to buy a coin when it just came out and is worth very little, if it were to increase in value you could earn a lot without doing anything. Obviously the cyber criminals on the Net have released many totally bogus and fraudulent ICO offers. For this reason, it is advisable not to make any purchase if: there is no accurate or updated information of the company that generated the currency, we do not find any news on the Net about the company that issues the currency and if we notice questionable commercial practices, such as insider trading.
