It looks very interesting, though there are lots of similar products with the same goal. However, i liked the detailed description and the complete roadmap.

Hard Fork (Q2)
https://coindar.org/en/event/digibyte-dgb-hard-fork-3465

Very risky to hold DGB in large quantities better just hold a little, because in the year now has many tokens appear with a variety of concepts that fresh, it became an investor interest to jump directly into it.

this legendary coin made lots of "FOMO" generation,

There are a few coins out there that 'pride' themselves on being asic resistant. Vertcoin for example. So I don't think GPU mining will die when there are popular coins out there who intend to keep GPU's as the main form of mining.

Sure profitability might drop, by don't think it will outright 'die' in 2018. Also ethereum going POS won't help with hashrate distribution.

I was not sure before that dgb will hit 1$ this yaer but now i am pretty sure because DGB is getting listed on many new exchanges. More exchanges mean more volume, $1 Price is not far now.

Don't know if this is in the works but it is something that should be done because most investors look at how cheap the pieces are rather than the value. It is dumb but we gotta cater to those investors as a result I believe we will achieve our true value much quicker. The reason I advocate for bigger supplies is because look at how the big supply coins did in December and January they did amazing because noobs want more coins. Lets give them more!

Is there any reason why is Byteball still so undervalued? If we compare it to the IOTA or Raiblocks (which uses practically the same DAG technology), they have much bigger capitalization. IMHO, byteball seems that is a real product with a good features.

Bitcoin devs have to add something: Lightning to mention just one.
Until then it will stay in the 13K-17K region as December-January trend is demonstrating.
On Dec 06 BTC reached 19.697K high with an RSI(14) at 94.56%, which was just insane. Following three days (7-8-9) were in red, with lower highs and lower lows (in the <than 14K realm the lows). That was the end of the bullish trend. By the 11th ETH started its massive roaring. Not a coincidence.
BTC prices are deadly within Ichimoku cloud, which is still green, but this is a clear flattish signal, combined with a <50% RSI(14) at writing time. All data from GDAX.

If BCH by end of tomorrow won't be >2.715USD it will play in the same flattish league.

BTG at Bitfinex -as Bittrex uses USDT and Bithumb and other exchanges have been rightly excluded from the price by Coinmarketcap, see https://coinmarketcap.com/currencies/bitcoin-gold/#markets - is pretty close to the flattish territory, despite the massive today's jump.
The most worrying issue yet is that Bithumb now holds >60% of volume and price is more than 70 USD greater than the 359USD computed by Coinmarketcap, as I'm writing. So, yes, techically speaking BTG own price is pumped at Bithumb (NOT by Bithumb), and insanely pumped at Coinone and Korbit (all three with BTG/KRW trading pair).
This is NOT a positive thing, to use an euphemism, and these exchanges should NOT be used as valid references for BTG value and trend altogether.
Bithumb holding >60% of BTG exchange volume is a gravestone to BTG worldwide diffusion.

BTG has no future. only a fool would buy the coin.
if you don't want to loss better don't buy BTG

Bit strange that DGB hasn't hit the major exchanges yet, Spankchain manages to get onto bitfinex

My I ask why? I would like to see it go to the moon, but for the moment I don't see any indications of this happening.

I really doubt that. There'll be a new Bitcoin fork with the same Proof-of-Work algorithm equihash, called Bitcoin Private. It'll make Bitcoin Gold obsolete because it also has anonymity.
