bitcoin blockchain secure, but your client not totally secured.
Keep your private keys in most secure system, better mostly offline

Bitcoin core team working for this problem. She trying to add lightning network, bitcoin cash try replace original bitcoin with increasing size of block 2mb 4 8 and more, but its cant be contentious infinitly

Of cource most stable is etherium. Ether interest in their price stability, because this is fuel for smart contract platform.

My opinion need to create one more wallet only for airdrops and hold coins in them, that a large number of different coins did not interfere your eyes
Some times look into the wallet and sold pumped for the moment coins

For ethos ? or for mining generally.
For eth good nvidia gpus, Best ROI for 1060GTX
You need any mobo wich work with selected numbers gpu you want to instal in rig, any cpu 4gb ram and look seriously for PSU. Calculate power consumption of your hardware and add 100watts to reserve

I am use xmrig. Simple to use. Settings can be loaded from json config file, 1% dev fee. And can work without window.

Segwit2x can ba reallized on etherium network ?
What if original segwit2x (original bitcoin fork) has been succesfully launched.

Very soon nvidia releases new technology AMPER it will be stronger than vega arch

I think show is over. BTC price going up again

bitcoin core knows about network scalability at summer, and nothing to do for the moment.
Yes he win segwit2x by supporting community, but it cant be continuing ever. If he nothing to do something big btc can be die

they want to paid stolen balances from transaction fees. Its meant you must mine form zero and he have been hacked again

ripple is centralized system, he can be number one around centralized currency i think

Try delete driver then modify bios, and then install drivers to card with modified timings
