You are way way way overthinking this process.. You should just trade the chart you are trading.. Forget about trading it back into fiat after every profit.. just keep some ETH and some BTC and some USDT and trade all those alts that pair against them.. and if the BTC/USDT chart breaks a base and panics, then trade that pair independantly too.. let the market decide which base currency your working with.. but avoid unecessary commissions and over complications (moving money from alts to fiat unecessarily) I think thats all to stressful and complicated.. As long as you are making profit on every trade your account will grow very very fast, no matter what coins your holding
RE: Lets look at my recent trades, and where will I buy BTC, BCH, ETH next? Wheres the bottom???
