This is third article from my series (links to other two in the bottom). This method if timed right almost guarantees success but of course few things can always go wrong.
Exchanges
For starters register to Bittrex (usualy this one will have the ighest price) + Binance + HitBTC + Cryptopia.
These exchanges are +/- secure so deposit some BTC into them for the time when action is needed and hold some ALTs that you believe may have pumps as usual 1 exchange drives the pump and others are for arbitage.
Take your time, register there now as they dont need any ID verification and deposit some BTC even low number.
