I am really sorry if you are feeling I am not real person and create some confusion here because I am not here for anything wrong just for information, and you already provide good links which I will read and try to understand because few things are very important before jumping into any field but still I am really thankful for your kind information and other details. Just last thing which is a better way to keep my bitcoin safe because I check mostly exchanges needs personal information and I have no problem to provide them this all but is this safe to keep bitcoin on these exchanges or any other way is better, thanks.
I am not opposed to holding some value on exchanges (or with third parties. In some cases it might be practical while you are learning how to be your own bank), maybe up to a few thousand dollars, and surely for each person the threshold will be different in terms of at what point you are going to want to bring some (or all) of that value off of the exchanges.. and surely you should want to try to learn about some private ways to hold your coins.. so it gives you options to have your coins in private wallets in which no one can stop you from being able to spend them and other potential powers that you might have from having your own keys that may or may not be readily apparent or even something that everyone seeks for themselves, but on the other hand, there is always a threat of either rug pull or various kinds of locking up of your funds when 3rd parties hold your keys.
There are likely several different ways to hold your bitcoin, and Trezor is pretty good.. either the Trezor one (which is cheaper) or the more expensive Trezor Model T and you want to make sure you get it from an authorized source (or authorized reseller) and with trezor it seems better to use the extra word too and also maybe to have some decoy value that you keep on the regular section that does not have the extra word... and of course, it is up to you how you might organize the various accounts on the trezor and get used to it...
Passport and Coldcard are likely good too. but a bit more sophisticated as compared with the Trezor, and there are other members who like Electrum, Spectrum and Sparrow, but I have not really used them... and there are other wallets and forum threads on the topic, and there are some members who like paper wallets, but I am not really accustomed to them, either...
You can also use Bluewallet, but I am a bit weary of keeping too much value on your phone... and maybe Phoenix and Breez are good lightning network wallets, and maybe guys have other recommendations, and there are forum threads on a lot of these topics that could get in depth and just require you to figure out what kinds of tradeoffs that you might be wanting to make to ensure that you have your coins privately and that they are sufficiently safe from getting taken including being careful not to create systems that are so complicated that you end up locking yourself out of your own coins, since there are responsibilities in being your own bank that can sometimes not be exactly straight-forward in terms of learning or even realizing if you might be putting your coins in jeopardy.
Trezor is excellent. I can vouch for Model One (the original). T can maybe do more
altshitcoins better, but One is more than enough for BTC -- at least that's the way I use it. Just to reiterate (have covered this topic extensively in the past) that Trezor is just a tool for user-friendly access to your wallet. The actual wallet is the 24(+1)-word seed. It's not material. It's numbers in number-space. So, even if the physical device is lost, stolen, damaged, or even sunk in a failed seastead attempt or boating accident, your wallet is still out there, as it will always be, for all eternity, set in stone by math & science, and only accessible via the seed. It's the seed that one should secure and never lose.
Merit farmers came back again? They seem to come in waves...
Looking fwd to the next bull run, to see how WO will react. Gay Xmas cards? Choo-choos? Carolinas?
A few more years/cycles, and I can see WO data being downloaded and studied by PhDs in psychology. It's becoming a gigantic social experiment.
