btc cant do 10-100X in one blow can it I think basically no so I think just watch out for fundamental project and then if you get lucky into some presales then congrats they can actually make 5X or more especially from platform like daomaker or others Just search some ecosystem launchpad and get in early and you might do fine but if you want safe investment and just hodl strategy then keeping btc is a good idea
but we are talking realistic maybe you can speculate to choose ico in the hope of getting 5x. but the reality on the ico pitch today is not as hopeful as you say. nowadays ico is more like hell for investors and long term scam. so in my opinion the most important thing is to choose bitcoin for the safest deposit asset now and in the future
