Crypto caught the attention of a lot of bad people in the HYIP and what I first realized during the period of crypto run was that many HYIP started using crypto as part of their payment options in addition to other ones such as perfect money, payza, solidtrustpay and others. This did not stop there as many scam schemes are being created with the names of the scheme relating to crypto (e.g Bitdonate, bitconnect etc) while the payment processors being used were purely cryptocurrencies. If you have experience with investing in HYIP before you will know that those behind the scheme are very smart. Today I believe they are the same set of people creating many crypto-related project and throwing IEO on some platforms such as Latoken, exmarket, Crex24 etc. with the major aim of defrauding investors as usual.
