This will help me make a decision on whether to stay on pocket legends or try this out,

Pocket legends the gear it is 13million , it took me 5 weeks to gain that gold with 4000 dollars in platinum I bought after being a new player

On here I can easily buy a never ending supply of crates and open them until I have the best gear given that I get more gold on here if I buy it with platinum then what I get on pocket legends. If I were to spend 5000$ on here and buy my gold would I have enough for the best gear? Or if I were to spend money on gold and buy locked crates then open them how strong is the possibility that after a few thousand crates will I loot the best gear for my character or even more then expected?
