When forks happen we all know that the BTC price will drop. but that won't mean that we can't make a profit.
There are a few ways of making gains with the next BTC dump.
1. Going short on BTC
This could be tricky as BTC is not that predictable. some experience in shorting is requierd here.
2. Going into Atls
I would not recommend to go all in to Alts, but there are a few Alts out there who are about to go up during the 'crash'. Its always useful to look at the previous fork, and to keep in mind that people will learn from those markets also.
3. USDT
Tether is the equivalent of 1 dollar, so in this strategie you could sell some BTC when It is still high and that way you keep your value. rebuy then when BTC is on his lowest. and you will end up with more BTC
4.Personal opinion
I think it is best to make a combination of those 3 strategies. I also think that we could see a bear marktet for about 6 to 8 weeks before the fork in November.
If you are absolute long term that this may not effect you and you can perfectly just let it all pass. But the way I see it, the greatest opportunities are made when things are down.
Let me sure know if you have other visions or views on the coming hard fork,
Let the gains begin!!
