You are right that the altcoin season might come soon but not every altcoin even the new ones will also bloom. That amount you're asking is high and I don't think someone is gonna be brave enough to invest with the token that you've made. And having a guarantee of x3-x5 is something that many will surely be doubtful of. It seems that you've got some plans already on how you're going to do it but what I am saying is you'll be having hard time people in here to trust what you've worked on.
