Once that's reached and its on it's way to 200k it's going to become very difficult to accumulate for regular folks.
Difficulty of buying bitcoin is not affected by its price, the amount you can buy with the same amount of money changes but it will be as difficult or as easy to buy bitcoin as before even at $200k!
If you can jumpstart your entry by borrowing 10k, 20k or 30k from the banksters do it
That is a terrible advice. You should never invest what you can't afford to lose specially if you are a newcomer to bitcoin world and not yet familiar with how things work with bitcoin itself (such as how to use wallets, security, cold storage,...) or with the market (specifically the unpredictable short term high volatility).
Buy $20 chunks as often as you can, pay no heed to the price. Ditch your daily $5 Coffee - that's $150 of Bitcoin per month, stop the pizza delivery, buy $15 of BTC instead.
This is the only good advice in your whole post.
During the journey you may want to punt a portion of your BTC on an Alt you believe will rise greatly
This is another terrible advice, more so for beginners.
be careful though and do not panic if your alt crashes because 99% of the time they will recover to the price you bought in at.
This is a lie. In most case altcoins that get dumped will never recover to their previous prices ever, specially if the pump preceding the dump wasn't the first pump and if it was a big one.
