NTS is so unknown and with so low volume that it's pointless to look it serious. You can't make any correct analysis on a coin where 1BTC trading volume pick would move the price with XXXX % -/+. Just invest your money in some live alt or ICO.
I made over 1 BTC trading NTS from 700 SATS to around 1300 SATS.
I guess you are using 0.5 btc for buying NTS so you can make over 1 btc because the increase of the price is almost 100% and without using a big balance, you cannot get a bigger profit too. Congratulations to you and I hope that you can get another profit from the other coins.
Yes, I see that the crypto market was moving to a better situation and many of the altcoins has increased in this month so we can hope that the bull market will happen soon. Just watch the market, make a buy and sell again if you think the coin can increase higher in the short time, don't be too greedy because you are expecting to make a bigger profit.
