Hi guys, i store a big stash of bitcoins that i earned from altcoin trading, on Tails.

I noticed that Electrum uses urandom function of the linux package.

But TAILS is having a problem with that:

Is it safe to use ELECTRUM in TAILS?

From what I can read in this github comment Tails fixes the entropy problem by using haveged

So you should be ok.

If you find my post useful send some BTC: 167XM1Za8aG9CdbYuHFMpL2kvPsw6uC8da

No its, not because it uses the same seed every time.

I`m also concerned about this ,especially in weakened hardware processors.

If you are concerned just move the bitcoin to a good hardware wallet like Trezor.

+100

If you own more than 5 BTC - it should be on a Trezor (or KeepKey).  You can still use Electrum to transact, but at least the keys are protected by hardware.

`/dev/random` and `/dev/urandom` are the best sources of entropy on a PC. Any other technique can only match them or do worst.

Don't stop where the ink does.
