Well you could make but not from bitcoin directly. You can still make money with altcoins but sadly not with the SHA256 ones because of the ASICS on the market. And as for SHA it's true that you could try but it certainly would be a waste. Let's say the eruptor mines at 330MH/s which means that it would earn around 17 satoshi a day... https://alloscomp.com/bitcoin/calculator here calculate for yourself.

Ok so from what I learned so far the block chain contains the transaction history. And without the history we can't validate the blocks. So even if you want to clear the transactions that are already spent you would have problems because without them the blocks are not valid. Also when I began with BTC the chain was only around 14-15GB so it wasn't that big but seeing that now it's like 100GB+... even if we did a hard fork to clear transactions from newer blocks we'd have problems because of the number of nodes. Also I think that the 4MB block size is absurd but we surely can't live with 1MB anymore. I think the community should have the right to control the size but then number of those who are not having the full chain is high.

http://bitcoin.stackexchange.com/a/19288 there you can find https://bitcointalk.org/index.php?topic=181981.0 where you can find a software that can make you one.

Has anyone succeeded to do it? I've installed qemu and lots of other stuff (c libs) and all it does is crashes... According to stack overflow you should be able to run x86 or even amd64 apps on arm but it doesn't work...

Yeah the current block chain is around 100GB. Well with port forwarding you could let the server connect to your mac (through your public ip) OR through a reverse SSH tunnel (I'd prefer this because you wouldn't need to open a port on your pc). but your mac would have to run all the time it's needed. Also I'm sure you can set ip white list in the config files (for more security). Then for PHP I don't know I've never used any like that but I'm sure you could find some.

Make sure you have around 100GB of free space https://blockchain.info/charts/blocks-size. Then you will need a headless bitcoin core. (the bitcoind)

According to some sites I found (https://pietrotech.wordpress.com/2015/01/16/odroid-xu3-first-steps-booting-from-sd-card-odroid-vu-display-issues/) you can just insert a properly formatted SD and it will boot. So you don't have to touch the internal emmc. btw you could use the internal memory to store data between sdcards.

Well I'd recommend using some 3rd party API and wait for at least 3 confirmation so it's sure that the btc has arrived.You could also run a wallet and check it periodically whether new transactions have arrived and if they did then track them until 3 comfirmation then you can be sure that it's arrived.

Hi!

I have a pi3 too with a 2.5A power supply (previously used a 1A one) and what I felt is that just the pi itself uses around 0.6-0.8A when used. I'm not sure about which USB miner you want but you only have around 1Amps from a 2A power supply. Also please note that the voltage will drop when you're putting load onto the charger. I'd recommend looking for a miner that eats 1A at max.

Well technically you could make a wallet on top of the RPC protocol and run the RCP cli in the background. This way you'd only need a GUI which isn't that hard to implement.
