How to get Ruby in Crypto Treasure

Here a question poops up " can we get Ruby for free " The answer is yes , we can get Ruby for free So how can we get Ruby In my knowledge currently there are 2 ways to obtain Ruby in Crypto Treasure 1 ) Buy it from shop , which currency cost's about $20 by the time I am writing this . 2 ) luck , yes luck recently one of my friend got a Ruby from special chest after opening 100 chest . I didn't count how many chest I opened to obtain the Ruby but it took long time . So what should you do Well option 1 is not a option to follow even if you have tons of money unless you want to waste , you should not follow 1st option it not worth it . You get 1000 PHT from the chest Currently 1 PHT = $ 0.00004 , 1000 PHT = $ 0.04 what price of the Ruby is $20 And for 2nd option as I said luck wait and be patient one day you shall get it one day .
