TWITTER is really a good platform for spreading a word about the ICO's . And the account with minimum of 10k to 20k followers are also good one to promote the ico's ,but here you are having more than 240k followers which is a really a good option for you to participate in Bounty and other ico projects.But make sure that you have twitter audit of more than 50% if not then it will be consider as Useless followers which counts 50% of Bots. Always maintain a twitter account with twitter audit of more than 70% to 80%.
if 80% not bad because followers more than 240k
