No, this is not to late to start invest in cryptocurrency.
This market is friendly to buy and good time to start invest.
Because i have the good feeling if price of all coin will get increase in December.
This is so clear if we look a data laat 2 year.
I don't sure that market can be friendly to anybody

And we can not see any growth till Dec '20.
But now it's not a bad time to enter. Watch on the market - red color there. And it's not definitely to buy BTC only. I'm sure some coins like OMG, ONT and other will restore own price faster than BTC
