Recently, all new hyips (but not only the new ones) which want to attract investors use to give a special bonus.
Now there are four major type of bonuses:
1. Bonuses given to you which are already invested in a plan and you can withdraw the profit made by them without investing (these usually are low bonuses)
2. Bonuses given to you which are already invested in a plan , but you can withdraw the profit made by them only if you invest.Usually they are higher bonuses but invested in the worst (cheapest and longest) plan.
3. Bonuses given in your account, not invested in any plan , but you must invest to whitdraw them or you can invest them too after you invest from your deposit method.
4. Bonuses at your first investment. Here are some things about them:
1st: They are usually invested in the longest and lowest paying rate plan. Considering the instabillity created by the scam hyips which appear due to more cheaper hyips scripts, many hyips fall because they are not rentable for the webmasters anymore, so at many of these hyips who offer 1st type of bonuses you will never withdraw the entire profit, just a little part of it. ***Also the webmasters use to give 1st type bonuses and after that modify the site so you will need to upgrade to withdraw (turns 2nd type bonus).eg: online-capital did so, but is a trustfull hyip so long.
2nd: These are higher bonuses, but you will need to be careful cause most of the hyips don't let you to invest in the same plan.(usually this is the plan with the lowest minimum invest).
3rd: These are usually practiced by scam hyips (not saying all hyips with 3rd bonus type are scams!!!). The scammers attract a lot of people who see a sum in the account and want to whitdraw it, but don't pay. Also they have high "minimum invest" sums.
4th: They usually are a part of your invested sum(which can be a very high one). Therefore, the conclusion is that bonuses are not what they seem, they are marketing strategies results (used to attract investors), and also on many sites they are given up to a number of investors or time limited. And at many hyips webmasters attract investors with bonuses and after that modify the minimum payout ( this is not scamming, and sometimes they usually have good reasons to do so).
Remember this things next time you invest in a hyip program which gives bonuses, but you know how they say: "No riscs, no wins !"
