Hey guys! Wanted to ask if someone of you know any good examples of instagram account management by some crypto project with atleast 5k subs (ICO`s are welcome) 
Your question is quite general and I haven't still understood about it. You want to join in Instagram bounty campagin of ICO project with 5k subs or something else, don't you??
No no, you got me wrong. I just want to take a look to a well-managed crypto project instagram account. And not crypto-related (like news or something) but crypto company itself.
You can look into the tokens and ICOs sections, you will find many campaigns there and you can judge for yourself which ones are well managed as per your own needs.
