Well let me share with you that i have made alot of money on these hyips because you need to know when to come into them.
Let me give you an example with hashocean , they operated for a long time . I made alot of money with them because i was there in the beginning i deposited a bitcoin over a year ago there , and everyday i would get 0.02btc for over a year thats about 7 bitcoins .
I always new they were a gamble but lets face it everyone knows . Its just about getting in at the right time.
Once i made my initail bitcoin back everything afterwards was just pure profit.
I never reinvested because i did not know how long it would last .
Most good sites last quite awhile especially the ones that have advertining as well on there sites.
I found a new one that came out a few days ago and has paid our everything so far .
Is it a risk ? for sure , but there are good odds of it making you money because its so new .
see the top banner on my website for the details on it .

They can't be considered as gambling,
But HYIP do have the same risk or much more in comparison to gambling,
If you do know when to join and when to quit then HYIP is good for you, but if you continuously invested into it then you will be a victim of scam later on.
While in gambling, You put your money at stake knowing that you have a 50% chance of winning or losing.
I think it's about gambling too. Because we risky our money into HYIP and gamble is the HYIP will scam fastly or we can still withdrawal our money.
