Is it too late to invest into cryptocurrencies?

I’m a skeptic.

I keep telling myself that the concurrency boat has long sailed and it is too late into BTC/ETH/LTC/etc. However, the crypto currencies continue to prove me wrong as they are still marching towards new highs (and almost at a daily basis). The crypto currencies appear to be resting before making the next move, either up or down. Either way, prices have calmed down in the past few days.

At this point, I’m thinking of pulling the trigger and getting my feet wet soon. Could use some help from you guys.

Any tips?
Do you guys think opportunity still there?
What cryptocurrencies do you recommend?
