Well, I haven't been to FreeBitco.in for a few years. It turns out that right now I have 10k satoshi in my wallet and I earned 0.04506873 BTC in total through my referrals with whom I shared like 0.02440395 BTC. I have 120 referrals since the times when I had been actively using this facet, and a couple of my referrals are still active (this 10k satoshi came through them, most likely). Just in case, sharing referral commissions with one's referrals was my idea
wetsuit hasn't been active since July 2018. Is he alive?
Great amount of money, if you have been more active with the referral I'm sure you'll earn a lot but that amount is now better considering bitcoin has some significant increase, would be luckier if you discover than during bitcoin high so you can enjoy your referral earnings more.
