Hello guys please can we share our view whether it is profitable to go for crypto-currency mining now or just hold till the price begins to gain it's upward trend!!!

It's not profitable and i guess you can try to do some effort by visit the altcoin mining section of this forum or try to visit cryptocompare forum to get the more reliable data to help yourself to get the best answer.
The difficulty was increasing a lot. If you are using some mining rigs and that will never be profitable. At least you can try to calculate it through use mining calculator.
