If you want to invest in BTC you should do it right now and please don't wait until after August 1. Wanna know why? Because now is the right time as BTC price is low, grab this opportunity now. I believe that bitcoin price would goes up and up after the split. If you invest 15k divide it by three buy bitcoin now for atleast 5k then if price drops buy again worth 5k and wait for the news and monitor the price on August 1 reserve your last 5k for a better timing for you to have a good return.
