When we read article on mining, we get a term "solving mathematical puzzle". To get a block, miner needs to solve the mathematical puzzle and whoever can solve the puzzle will be able to get a block and thus the reward (I can be wrong technically, this is what I know).
What's this puzzle all about? What do miner exactly solve? Please try to avoid technical term if possible, I would like to know in easy way.

I have no problems seeing a bright future for BTC, but after a major retracement it might again take many years to recover. Look at the last sell off down to $3700. It took almost 4 years to make new ATH.
So should this be the major, expected drop, it could again take many years for BTC to reach 100k.
Many people will be dead before BTC will reach 1 mio.

What are the chances of a bank closing your account if you buy bitcoin? i have heard people say they closed down their bank account for buying bitcoin, but this might have been a few years ago. he only said they closed his account, there is no chance of them taking all the money in your account, correct?

In that report it says "Use a resolution of the screen bellow 1600x1024 and press Ctrl+f to open the Bisq Filter tool." What does the filter tool have to do with it, I saw nothing in their that would fix the probem,

Ok so there are people who say that crypto is decentralized and cannot be controlled by the government. How can this be true when the government can shut down the companies or networks where you are able to buy, sell, or send crypto? What do you guys think? Do you all think that crypto is truly decentralized and cannot be controlled by the government or can they? Maybe not directly but indirectly controlled?

I couldn't find any real reviews about this dice site hopefully my review will help !

I got brave with Live support MIA I went ahead and made a deposited. approx 200 dogecoin value at that time about $80usd.

My deposit arrived and was added instantly to my balance as expected. I had some questions but live support was still non existent and this started to worry me but i played on and with a auto strat i left running over night i turned the 200 into over 2000 doge. So i made a 1000 doge withdraw value about $400 . support was still MIA but the withdraw was sent! It did take 48 hours but im relieved its legit and not a scam site.

I also then took the remainder of my balance up to 3000 doge with the same strat . I'm from usa and didn't use any vpn i think this is important at this site. If anyone plans on using the site.
Here is a non affiliate link to this dice site   sicodice.com i do have a affiliate link i just dont want to dilute my review.

Well I do think you can very easily use crypto Gambling overseas and instead of your bank accounts you can use bitcoins or other cryptocurrencies and sell them p2p. Yes ofcourse you should not go against the Government. But that does not stop you from finding loopholes, does it ?

Maybe you are not lucky enough, I did the spin quite often there (not really on regular basis) and sometimes get decent prizes like doge, xlm, and trx. On the other hand, I believe other prizes that start from 5 xrp to the left side are just bait or decor.

I doubt that will occur since they have BCD already and as we all know it can be converted to any of our desire coins.

You still have a chance to get what you want,

WOF has 15 prizes;






the last quote (group 4 and 5) is very rare, as I know when I look at proof from a member who got the prizes, the top quote (group of 1,2,3) is always seen every day here.

Hello,

does anyone here have any experience with using multiple betting accounts without documents from friends? I have some questions and would be happy if someone could help me with that. Ive been limited on some betting accounts and would like to create more (obviously cant with my own documents anymore and dont want to ask friends for documents).

Greetings

Alternatively, start bitcoind with -dbcache=2048.

Definitely a CPU bottleneck... the download of the data is only a small part of the syncing process... it's the actual number crunching of the block data to verify it (and all the IO read/writes) that will be making the Pi slow.

From a review of the Pi 400 that I saw... they had put in a large metal plate to act as a kind of heat spreader off the CPU to try and dissipate heat...

And from a write-up testing this cooling solution, it seems that this heat spreader actually does a better job for the Pi400 than a standard Pi4B with a cooling fan!

So, it'll likely be a combination of "low end" CPU + Disk I/O that is slowing things down, tbh.

I have my .bitcoin directory on SSD, and inside it is a symlink that puts the blocks directory on HDD. That's enough to remove the HDD as bottleneck, without taking too my space on my (much smaller) SSD.

What are the ram/memory specs of this unit? Is that 4GB ram?
Follow the ranochigo suggestion and put dbcache in bitcoin.conf file with this setting "dbcache=2048" only use this if that raspi 400 has 4GB ram.

Another suggestion if you want to speed it up more there is a big increase in performance if you switch to SSD as your storage. I know HDD is cheap but if you want to run a full node and want it to speed up the syncing process you need to switch to SSD.

Or borrow SSD from your friends temporarily until you downloaded the whole blockchain and transfer them to your HDD.

Bitcoin Core has a parallel download during the IBD with the headers-first synchronization. The speed shouldn't be solely limited to a single peer as the blocks can be downloaded in no specific order, as long as the block hashes are in the headers on the best tip.

Now, with Raspberry Pi, there are several bottlenecks, the USB port (for the external HDD) and the CPU speed. The CPU speed is probably your main problem; Raspberry Pis are very underpowered and it would take days for a completely synchronization without assumevalid (in my case) but some script validations are skipped with assumevalid. Bitcoin Core still has to validate the blocks, transactions, etc and also build the chainstate and index the block. These are heavily reliant on your CPU which is unfortunately not an area Raspberry Pis excel in.

What I've done when I ran a node on my Pi is to synchronize on my actual computer before transferring the entire directory to an external HDD and point my Raspberry Pi's Bitcoin Core datadir at it. This skips most of the heavily validation on the Pi and reduces the time taken for it to be up and running.

Lately, I have some list of top coins that haven't hit ATH perfectly yet. My choice is the BNB, LTC and BTT coins have the opportunity to reach new ATH, I am not not suggesting BTC and ETH but the current price is still too high and maybe you can buy it if the price is corrected below.

Hello community here,

I am newbie here and happy to join here.

My ask is what will be your advices about keeping a coin long term ? Which coin is worth for it?

any ideas will be appreciated.

Thank you all, what I understand is that i am expected to give my name also along with UPI ID for selling btc or else no one is ready to trade in phonepe.

Sure,  Everybody have USDT.
Its a safe heaven currency.
