I think that the point is that if a person is either brand new to bitcoin or considers himself to not have enough bitcoin, then he has to buy bitcoin in order to be prepared for UP, since he does not know if the BTC price is going to go up or down.
If any person joins this market with purchases and with a belief that Bitcoin price will go up, up, up and up, it's terrible thinking and horrible start. Bitcoin market is similar market, which can not rise forever and has up and down, bull market and bear market. Any people join Bitcoin market must know about it, and be clear about why he buys bitcoins, how long he can hold his bitcoin after purchases. It requires knowledge, and strategy for buying and holding, not simple.
If he does not buy, then he is taking a chance to want to buy bitcoin at lower prices than the current prices, yet those lower prices might not happen. If they happen, then is that when the buying starts?

A new person does not need much to invest in Bitcoin. As you said, if a new person is willing to learn or gain knowledge about these things, then he will never be able to start investing. A new person needs to start investing in the first place, if a person has basic knowledge about Bitcoin, faith in Bitcoin and a source of discretionary income, then he can start investing. If a person has these things in his mind and waits to invest in order to gain more knowledge, then it will never be the right decision. A person needs to start investing first. After starting investing, a person can gain more knowledge in a deeper way. Waiting to invest in order to gain knowledge will never be the right approach. It will be better for an investor to learn the things you mentioned after starting investing.
How long does a Bitcoin market cycle last? No one can ever say. Because Bitcoin is not under anyone's control. Bitcoin is not controlled by any person or bank. If there was a person or bank controlling the stream, it might have been said.
