Just to be fair, Freebitco.in is one the best faucet site which also includes lottery and betting feature. The Introduction of Interest on the amount kept at freebitco is one of the unique feature which no other faucet site offer.
Also you can search youtube and get unique ideas on how to Autobet and get nice profits on bets.
It looks like you're new to gambling and that's asking people to play on this site to increase profits. It is one of highest house edge site (5%). You will never make any profit from this site, and all those videos are edited because they are showing you just winnings but never show you the losses. So don't believe them and lose your money. Even on 1% house edge site it 's hard to win money from this dice game, but with 5% house edge, it is impossible to earn money. If you play on this site then wasting your money.
You are right. 5% house edge is too much that no matter how much strategies or techniques you apply, you will not be able to beat the site. The youtube video on this are just fake and people make them just to increase their Facebook channel activity. The only good think about Freebitco.in was for the faucet lovers but that too they are lowering the rates of claim with bitcoin price increase.
