I'll kick start this.


0.04BTC

Even if one miners don't shutdown, if 50% of the network shuts down, a 51% is more likely and transactions would process slowly as the difficulty is too high. Also, difficulty change would take lots of time since difficulty changes every 2016 blocks.

Use ASIC for them. If you use a fan and a heatsink attached to it, it would have a longer lifespan. But if you can't afford to buy a expensive cutting edge ASIC, you probably shouldn't mine.

It is not recommended for newbies. Electrum do not officially support android and incompatibility could happen, resulting in loss of coins. It would be better to go for a wallet that is designed for use on Android.

After all the blocks reward is mined, Bitcoin will survive solely on transaction fees. At that time, the price of Bitcoin may be higher or lower which would either lower or rise the transaction fees respectively. By that time, hardware advancements and renewable energy would make it profitable to mine. If it is still not profitable for those paying electrical fees, those who do not need to pay for electricity can then mine more profitably due to difficulty drop.

If one does a disk wipe, it may not be lost unless data is write over it. Even if it's recoverable, it would take lots of money.

OP probably didn't understood how does Bitcoin work and treated it like a bank account. Private key is the thing that you need to spend your Bitcoins, not your address and wallet encryption password. Without a backup, you won't be able to access your coins as you won't be able to sign a transaction from the address.

Trading is even more risky if you are inexperienced. Even experienced people lose money at times. Trading is like gambling as it's all about luck, it may just crash any moment. One wrong move is what you need.

You spelt it wrongly. It should be 'scrypt' instead of 'scrypy'.

Ghash.io offers a pool that focuses on scrypt mining.

Stunna has already mentioned tips are not reversible. It's your own fault if you make a mistake, don't expect stunna to refund it since people could easily SE him. You should always double check before sending.

It's worth noting that by using Tor, you are risking the possibility of a 0 day exploit on https. People have been hacked like this. Unless you really want tor, try private internet access or don't even use VPN.

Antviruses aren't safe enough. Viruses can still sneak pass the detection. the best way is to never download any suspicious program or even better, wipe your PC before making a paper wallet.

You could potentially messed up someone due to the lack of knowledge in Linux. Linux isn't as user friendly as Windows in my opinion. As long as you install updates on Windows, a freshly wiped computer running Windows shouldn't pose any threat to your wallet.

I suggest OP to use a paper wallet and laminate it. It would pretty much prevents most damages. For safety purposes, make copies of tjemand put them at different geographical locations.

Not necessary so, for example, hufflepuff from primedice won 1000k+BTC and never went below profit every since. The 1% house edge would ensure investments to have a 1% profit overtime not guaranteed but it is bound to take a long time.

Also, if you have too much inputs, your transaction size will rise thus also rising your fees for the transaction. You can still possibly send 5000 sat without a fee but it would probably not be confirmed and dropped from the memory pool as transactions only above 0.01BTC are considered to be eligible for free transactions.

It is practically impossible for one to generate all the addresses available without a few thousand hardware from the future (few hundred years). Why would someone even want to try it? It would just be a waste of resources.

It is pretty hard if a transaction is left in the open for sometime and has been propagated well. It prevents the most simple type of attack without confirmation. If you have one confirmation, it is nearly impossible to double spend without 51% of hashrate. For larger amounts, more confirmations would be recommended.

That is actually true. Most mining software's disables GPU by default considering their efficiency. If you want to experience mining try cgminer 3.7.2. You can find it here: https://litecointalk.org/index.php?topic=14809.0.

Transactions can be reversed even after 6 confirmations. Dont take it as a insurance. If one entity controls 51% of the hashrate, he could execute and attack which would allow him to reverse transactions with 6 confirmations and above. However, the more confirmations it has, the lesser chance it can be reversed. The problem is most people can't afford to wait for 6 confirmations. Which can take up to one hour or maybe 2.

With lots of luck and high hashrates, you could try to solomine and find a block. There are places which both electricity and rent is cheap.

You would honestly just be wasting your time. A lottery would have a few million more chance to win than finding a collision. Basically you are playing a lottery which is impossible to win unless a weak key is chosen like 1 as the user said above.

Why would it be rare? There are plenty of merchants with bitpay implementation accepting 0 confirmation transaction. A double spend is not as easy as you think. As long as you wait 30 seconds or so, connect to well connected nodes and the transaction is well propagated, a double spend is unlikely but not impossible.
