If they think about investment, maybe your suggestion will work. But a lot of people buy bitcoin because they think if they can get instant profit in shortest way. That is why they gamble, or maybe do trading activity without any skill or knowledge about it.
With gambling and trading risk is very high, I know that many people decide to try their luck with one of these two in order to make fast money, but what's happen is they get busted after some time. Those people who decide to do that, usually comes here on forum after losing money to complain about certain services, exchanges, casinos and entire crypto.
Its why education is important, why researching is essential, if they come here on forum before everything they would see numerous topics about possible risks in gambling and trading. Numerous advices how and where to start with crypto.
A lot of people maybe have their strategy to earn bitcoin, only a little from new people will look information about the forum. In my local facebook group, a lot of people ask cloud mining which is still paying, actually maybe they know it is risky but they want instant money from it.
Well to pathetic for that guys to still look after the cloud mining services since it has so many scam events happen and we cannot even deny that almost all of them turns scams when they accumulate more funds. Better to tell your group mates to buy bitcoins at this time since it's more profitable rather that engaging their selves on risky investments.
We know in facebook group of bitcoin usually there are people who suggest other to not trapped for something like that. It is already happen, but i think it is depend on that person, if he only want to look for something like that (cloud mining, or maybe double triple bitcoin) i think we can't force them. At least we already educated them.
It`s paid advertisement, or simply investors seek for referrals. Two possible ways to earn with HYIP`s, to advertise it and someone to pay you for that, or to not invest anything but to have many referrals that will invest some money and that will generate profit for you.
I`m not sure who is still trying to make profit with investing in cloud mining services and hyip`s, probably newcomers, fresh blood. Old crypto people are staying far from this services that have big promises, in most cases that`s a big trap, if not in all the cases.
Well education is the only solution, people need to learn how to do some research, to learn about something before they invest their money. But most of the people find it boring to read what we wrote, pros and cons about services around that we tried, they simply wish for fast and big profit, and that greediness is the thing that ruins them in short period.
