Running until May 7, 2018, 21:59 (CET) - If you are on my whitelist and don't want to solve the 'second' puzzle you can request a direct link to it (as I haven't found that option on sgtools).

So ... again a little train:

2.) 5KM1NzNkmRtzcZXKTzmWLwFTH7L3EBPTUXaMN12kx8eKeqVHqJb
1.) 5JhkHgH2t2uwgdCrT322CyK1pVdiaKzFtBu4npEEfW83ZurPkq3

Hint: Maybe this and googling those prefixes will help.
This page might help you and this one might be interesting, too.
You will get something and have to use the first ? letters != 1.

Hint 2: A pseudo-code to solve the puzzle:
PUZZLE(5KM1NzNkmRtzcZXKTzmWLwFTH7L3EBPTUXaMN12kx8eKeqVHqJb, 5JhkHgH2t2uwgdCrT322CyK1pVdiaKzFtBu4npEEfW83ZurPkq3)

(1) PUZZLE (info1, info2)
(2)       pubAddr1 := CalculatePublicBitcoinAddressFromPrivateKey(info2);
(3)       pubAddr2 := CalculatePublicBitcoinAddressFromPrivateKey(info1);
(4)       sgtoolsLink := "http://www.sgtools.info/giveaways/???3c???-4f09-11e8-b5f5-fa163ee2f826"
(5)       sgtoolsLink.replaceFirst(???, FirstNonOne(pubAddr1, 3))
(6)       sgtoolsLink.replaceSecond(???, FirstNonOne(pubAddr2, 3))
(7)       return sgtoolsLink;

(1) CalculatePublicBitcoinAddressFromPrivateKey (privateWIFKey)
(2)     return justPasteItInWalletDetailsOnBitaddress(privateWIFKey)

SGTools-Rules you will here encounter:
