First things first, no one missed out on BTC, if you are reading this and you understand this world, then go immediately buy some, because BTC growth is not over, not even close, it´s just a baby... (not a financial advice, mere especulation).

The other point I would like to refer is the fact that if you are initiating you definitely should start learning all the basics and always invest in BTC first, so you make your first mistakes in a coin that has potential and already showed a lot of value. Plus the fact that inside this "crazy" volatile markets BTC is probably the most stable coin, because all the others variate in concordance with BTC price, but in a bigger percentage (except USDT, Tether).
