After the fork, people will be dumping BTG as fast as they can and the sell off of bitcoins will be huge. Money will flow back into altcoins because they usually produce higher profits than bitcoins, percentage wise. This cycle has happened over and over many times already. It won't change this time around.
Well surely same scenarios will be seen after the hard fork. People dumping their btg and buy some alts that's really promising that's why the money flow will just be surround here.
The fact that people are holding their bitcoin now is to have bitcoin gold, well everybody loves free money.
But they are also paying a very high price for the BTC now. Unless BTG ends up being worth a lot more than most predict, buying BTC the last few weeks was not a good idea. Unless it was to turn right around and buy alt coins. I'm guilty of buying a bit high too. I paid as much as 4900 and my average price is about 4300. Seeing it hit $6200 makes me feel a little better knowing there is a decent buffer. I'm in BTC for the long haul anyway (3+years). I put a lot into alt coins as prices tanked. So many cheap ones right now. I might sell 1/4 of my BTG fairly quick and then wait a little to see what happens.
