I guess the answer is C.
How can I receive my coins?

I read the posts here and the metioned White paper, and they try answer all the few question, what was asked here.
I won't invest more than 1% of my money to any ICO, but I collected some coins in promotions like https://www.coinbase.com/join/5c3763b6bc9d990e8751b8af , https://etoro.tw/2GYVGhz wallet and https://ddex.io/referral?referralCode=U6JB so I will risk my "free" coins to invest in project like this Maxicredit.
