nobody in their right mind would use btc for transfers;

if you're using arb bots set them for some other coins, if you're not playing both sides (I don't, because I like the adrenalin while waiting for confirms; I do arbs for that reason only); btc is transferred only once on a particular exchange, after that your wealth is stored in btc; for transactions, choose fast confirms, liquidity, stable coins (so that you don't end up on a wrong fork or so) etc.

your beloved quark is good for fast confirms, but is not available everywhere; zet is fast, has good liquidity, good for big amounts, but is not available on small exchanges, unlike drk- you can find it almost everywhere (and the liquidity is still pretty good); myr is perfect for small exchanges (and small amounts).

doge is my favorite transfer coin, it has everything; however I have noticed that confirms are somewhat slower now then couple months ago.

btc is gold, and should be treated as such; use other coins for transfers, make a list of coins with good specs for trading and use them as a currency- the way you would use fiat when trading stocks and commodities;

bear in mind that you should follow your 'currency' coins, the way you follow your coins on a pump; my list of these coins was somewhat different 1 month ago, significantly different 3 months ago, and completely different 6 months ago;
