I'm going with one thought on my mind, "How to earn something without investing anything or very little", so I don't get into any situation like you did.
if like you said:"How to earn something without investing anything or very little" then my U2cloudmining is made specialy for you
The first investors have now invested 50000 satoshi or so FOR FREE
it is based on a real econnomy and "market regulation".
It is now a little harder to get free shares.
tomorrow or in a weenk perhaps even more harder,but perhaps more easy.
it is the "market" who will regulate it.
You have absolutly not to be careful for claiming for free...
you have just to decide if you claim or if you do not claim for free.
If you do not claim...other ones will do it for you and take the shares (or better said a part of your shares)
After we have not to forget that it is a game...where you can claim for free or sell for satoshi your shares with 10% bonus.
You and only you decide what is better for you.
After ok...for investing with your own satoshi you have to be more careful...I agree.
I agree because one do not know if the shares will be profitable.
if you lose 5% of free shares it is not a bit pain...but 5% lost of invested satoshi is painfull.
It is why I want to add:
beginners be very carefull about what here is writen...
many systems are scam...but not every ones.
