I think you are getting something wrong here. Bitcoin is the crypto itself. Every other coins you see today were built around bitcoin. Many people only know bitcoin when they hear the word crypto. There are people out there today who doesn't know that other coins exist, so when they hear about crypto the first thing that comes to their mind is bitcoin. Bitcoin is the crypto currency, if you are not aware of this know it today. If he had mentioned alt coins then you can say he is referring to other coins. So @Michelle is not talking out of point when he used the word crypto. If you see a newbie that has no knowledge about bitcoin investment, ask him or her what is crypto, I bet you the person will mention bitcoin.
What do you mean by saying '
Bitcoin is crypto'?
Everyone knows that Bitcoin is one of crypto coins. However, if we are talking about crypto, it will be a general matter. We are here talking about a specific thing, it is about Bitcoin. Sure, all altcoins can't be separated from Bitcoin, they are always depending on the trend of Bitcoin. But here, we aren't discussing about the correlation among crypto coins. We are analyzing the price change of Bitcoin, we determine when the right time for buying Bitcoin. I think it is the point of this thread. CMIIW
