for now I suggest switching your ltc to btc. this is possible to speed up your profit than you have to wait until selling ltc at the price point you want. now ltc is very difficult to experience and is still in place

This must be the first battle of stable coins topic I've read in a long while.
I'm just curious, why would you want to store a stable coin?

To choose which one, I would avoid the shady USDT for long term storage.  

I am usually quite confused about this halving sometimes, despite the little knowledge I have about its reward, some people believed this is the time price of such coin goes up, but from your point, seems you believe the price will go down, if not, why would you be selling before halving when you are supposed continue holding till after halving when the price will skyrocket.

Well, I am not an holdler of LTC so it would not really be a bad idea to me if you sell your LTC to bitcoin because whatever action you take as regards bitcoin investment will definitely ay you more than any action you take in LTC.

Ok... so going back to your original post, it seems like what you're actually thinking is "how the Ledger can "sign" a transaction, without accessing the private keys?".

The short answer, is that it can't... it absolutely MUST access the private keys. However... the trick to the Ledger is that it has the "secure element". This is basically a mysterious "black box" containing all your private keys... the black box can see/access your keys... but no one else (including you) can. So, the idea is that you put in an unsigned transaction... the black box does "magic black box stuff"™ and a signed transaction comes back out.

You can't see what is in the box, you can't access what is in the box... the box will only accept an unsigned transaction^[1] as input... and will only give a signed transaction (or error) as output. It has a bunch of inbuilt code and functions and magic smoke that allow it to achieve this wizardry... but due to Non-Disclosure Agreements and lot's of secrecy... the only people that actually know exactly how the internals of this black box work are the manufacturers.

Hopefully that helps...


[1] - In case any pedants are here... yes, I know it will also accept "messages" for signing.

The "data" (in this case, the details of the transaction) is secured once the transaction has been "signed". After it has been signed, any modification to the transaction details will cause signature validation to fail and the transaction will be rejected by any node you attempt to pass it to. Likewise, if the data is NOT signed, nodes will reject it as "unsigned". You can think of the "signature" as like a tamper proof seal wrapped about the transaction details. Nodes are configured to reject transactions if the seal is "damaged" or "missing".

So, what happens is that you first create an "unsigned" transaction in the software that you are using in conjunction with your ledger (ie. Ledger Live or Electrum or MEW etc)... Note that this "unsigned" transaction is built using the public keys that the Ledger device will export to the software so it can determine which UTXOs you are able to spend (ie. which public keys/addresses are "yours"). The private keys are safely stored on the Ledger device in the secure element and are never exposed.

Once you're ready to send, the "unsigned" transaction is first passed to the Ledger device for signing. This is why it is very important to double check the info that the Ledger device displays, with the info being displayed in your wallet software... if the info matches and (more importantly) is what you were actually trying to achieve (ie. send 2 bitcoins to public key X), you "confirm it" by pressing the "yes" button on the device and then the device will go ahead and sign the transaction using the appropriate private keys inside the secure element, and then it will pass the "signed" transaction back to your wallet software.

At this point, the transaction can not be modified in any way... so, you're free to broadcast this "signed" transaction to the network, safe in the knowledge that no-one can modify it because of the "tamper proof seal"

Does it really matter? LTC will still be worthless. Will it ever find acceptance with corporates? regular public? Even the latest releases of LTC Core 0.17.1 doesnt boast of any noticeable features. So how can you guys expect it to bump?

Bitcoin is certainly more valuable than gold. It can do a lot of things gold cant do.

You tried with the brick analogy ... the only problem is that brick increasing in price would mean that:
1. Bricks become costly for  people to use.
2. Nobody would like the increase in price.
3. The number of people using and building with bricks will decrease.


Bitcoin increasing in price:

1. Bitcoin will still be affordable to anyone no matter the price.

2. Most bitcoin owners will like the price increase

3. The number of people using and building on bitcoin/crypto will increase.

You see why the brick analogy is not a perfect one?

you want coin suggestions aka shilling shitcoins but i will give you a better suggestion. you should stop being lazy and wanting to rely on luck and others and instead start learning how the altcoin market works. you are wrong about altcoins bottoming out. the altcoin market is a sea of shitcoins that get pumped and dumped and at all times there are some that have bottomed out and some others that are still dumping and some others that are getting pumped. the number of them in the last group is always smaller.
for example in the past couple of days ENJIN was one of the shitcoins that got pumped (mostly because of some arbitrary news). BNB was another that was being pumped because of Binance DEX crap.
there are lots of others that are getting pumped like this. you have to find out which one is good at that time and jump on board (both of these that i mentioned are already too late to buy)
