Tomorrow Bitcoin gold (BTG) is supposed to start trading. And there are many concerns, and one of them is
No Replay protecion
Without this people can lose their Bitcoin. This means that without this feature, splitting your BTC and BTG could end up you losing your Bitcoin. Most exchanges will not support BTG without this protection. Why have they not implemented it from day one?
There is a 300 BTG bounty on the issue, but only one developer working on it.
Right now, my theory is that Bitcoin is falling from the 6200$ high because the realization that BTG is not legit. It's legit perhaps in the sense that it's not a scheme. But it's illegit in the sense that it seems to suck. A lot of money has been flowing from Alt Coins to Bitcoin these past weeks. Now the market is realizing that perhaps there is not much to gain on the upcoming fork that is taking place tomorrow.
Therefore people are adjusting their expectations of "free money" and getting back into Alt Coins. Nevertheless, Bitcoin prices above $5000 is great at this point. I think it will build up a good foundation above 5000 (hopefully above 5500) and then we can go north from there before Christmas.
Target of 7000$ before Christmas is still intact!
Be careful tomorrow, and do NOT trade or send any Bitcoins before you have done GOOD research AND tried to transfer with a VERY tiny amount to see if it works first.
And as a reminder, what is Bitcoin worth right now with all it's past and soon to be forks?
Current prices:
Bitcoin core: 5700$
Bitcoin cash: 327$
Bitcoin gold: 400$ (currently pre-trade)
Bitcoin segwit2x: 1000$ (currently pre-trade)
Total value of Bitcoin: 7427$
Something to keep in mind.
