Keep accounts in different exchanges.

Follow BTC on binance.

As you see a drastic up or down quickly buy or sell on other exchanges.

Quickly put a stop loss of 10% of your investment.

Study other high volume coins movement with btc.

They react with btc price.

You need to be only a few seconds ahead and u can make profits.

Play small and master.

NEVER TRADE WITHOUT A STOP LOSS.

Dont think of making big money in 1 trade.

Strategy:

If Btc is ranging between 89250 to 89500 every few minutes,

And you think Btc will go down then:

You short sell a popular high volume coin when u see a prominent red candle stick on btc at 89500.

Keep looking at btc.

if btc turns green u quickly square off your trade.

if u see btc going over 89600 book your loss.

as u place a trade quickly - make sure that u quickly add a stop loss and profit in your modify/ edit order

(If not profit enter stop loss for sure.)

How to target a popular coin:

see volume is usdt

see if it is over priced.
