In case something really bad happen to crypto market in the coming months and Bitcoin drops to 200 - 300 dollars or lower.
Do not worry, that will not happen. The low trade at the moment is only due to the fact that it is hot and the people are in the summer holidays. Some have used some money for the holidays.
From the end of July, beginning of August, the trade will again increase.
No, the "low trade" right now is from uncertainty over the coming deadline for Bitcoin to either accept an upgrade or not which could cause two competing versions of Bitcoin itself. Since ALTS are in the Bitcoin market, anything that happens to Bitcoin affects ALTS. We will know more after August 1st but until then, just sit tight, it will work itself out as designed. This will all work out in the long run and ARK and other quality projects will go forward. Don't make any rash moves now without knowing exactly what you are doing!
