Is it true that the supra could produce 900 horsepower by adding a turbo.

Which is why it was featured as hero car in the 1st Fast n Furious.

Do you still play video games? What was your first favorite game?
Was it Tetris from the 80s, Sega Street Fighter 2 or Final Fantasy 7 from the 90s, WoW or Grand Theft Auto from the 2000s, or Fornite or The Legend of Zelda: Breath of the Wild from the 2010s?

Subaru with the boxer engine is the best, stability and reduced body vibration, handling is first class.

That's almost double the price of a Safe 5... Did you get it from an "official reseller" of Trezor?
^{- Their overall build quality is better than Ledger, but compared to their previous generation, it has slightly decreased (I already have "a couple of chipped parts" on my Safe 3).}

if ur price is usd then being almost double is absolutely correct, usd2nzd

How is it related to long-term holding?

Forget it. ref https://bitcointalk.org/index.php?topic=2415854.0 point-3

Holding Bitcoin for the long term without being tempted to sell is very difficult it requires a combination of mindset, strategy, and security measures to be able to hold for a very long period of time, below are some measures that will help you.

1. Backup funds.
Make sure you have an emergency, reserve and float funds, this funds will help you when ever you are in an emergency and you don't have finance which is what is needed, instead of dipping hands into your Bitcoin by selling it you can just use your backup funds to settle the emergency.
Having a backup funds will reduce the emotional pressure to sell during market downturns also.

2. Develop a Strong Conviction.
Understand that Bitcoin investment is one of the best investment right now in the world and holding Bitcoin for long term will be more profitable, and always remind yourself that Bitcoin is still growing and selling now means you have lost the future benefit of enjoying the big price.

3. Set a Clear Time Horizon.
Make up your mind and decide how many years you want to hold your Bitcoin if it is 5, 10 or 20 years, and tell yourself you will reach that time you have set for yourself, see your Bitcoin as an investment.

4. Surround Yourself with Like-Minded People.
Surrounding yourself with people who are also holding for long term are very helpful, since you are in this forum you can always visit thread where they discuss and encourage long term Bitcoin holding.

5. Stay Away from Daily Price Movements.
I'm not saying you shouldn't check the price movement of Bitcoin but don't do it daily to avoid being tempted, you may set a 10 years plan for holding and in the next 5 years you saw that Bitcoin has increased dramatically in price now seeing how big  your money is every day may tempt you to sell.
Check but once in a while.

6. Time-Locking Solutions.
Some platforms allow you to lock up Bitcoin for a specified period to prevent impulsive decisions.
This will really help you, when you have set out plan to hold for 10 years and you lock it for that 10 years you can only deposit more Bitcoin but  you cannot withdraw or sell it till that 10 years is over.

Not for the "rich" but for the "risk" takers..
Most people will say, “Only invest what you can afford to lose,” and yes, that’s the standard. But sometimes, if you truly believe in Bitcoin, you might go beyond the standard, just like CZ, who famously sold his house to buy Bitcoin back then.

Considering that there are a lot of issues with Ledger products, most users won't recommend any HW that is similar to them, so you should mention similar in what sense, exactly?
^{- I'm not familiar with Veracrypt, so I can't comment on your current setup, but if you're looking for a HW that you can use with Electrum, you can get any of the Trezor devices (preferably Safe 3 or Safe 5).}

Have you tried the solution that @dkbit98 mentioned in the latter parts of number 3 (using the phone camera)?

No one will know for sure when Bitcoin will experience a decline. When you start to invest, the doubts you have can sometimes be an obstacle. You should already know that Bitcoin will only provide good profits to you if you hold it in the long term. So there is no problem if you buy now. I understand your intention to get a lower price for buying, but such a strategy should rely on you having a large capital. It's okay if you wait for Bitcoin to drop, that situation will definitely happen. But I am not sure how deep the decline will be and when it will happen.

But the problem for newbies, if they are worried about the price going down and don't have the courage to invest now, will they have the courage to buy in when bitcoin corrects or enters a bearish phase? It's true that rushing doesn't help but I think for those who are still worried and don't dare to invest at the current price. That means they are not ready to invest, and if they are not ready, they will be less likely to invest when the price of bitcoin falls.

In my experience, because bitcoin is very unpredictable and anything can happen. Therefore, beginners should only invest when they are truly ready and only invest the amount of money they can afford to lose. And it sounds like OP isn't ready.

If you have a short-term perspective and you've already made some profit, why not withdraw some portion just not to miss the opportunity to take a profit while in an uptrend?
