We've seen this dozens of times before... Crypto price gets too high, China "bans" them... Cryptos crash and China buys them all back up to all time highs... Wash... Rinse... Repeat...
First of all, China is THE Nation that is benefiting the most from the Crypto Craze and huge rise in cryptocurrency and ICO's. So it makes no sense at all for them to try and stop that or slow it down, UNLESS, they were interested in creating a better buying opportunity for themselves.
Secondly, the greatest hindrance to the current cryptocurrencies is the dilution created by new ICO's being introduced every day. By creating a greater barrier of entry for new ICO's, that makes all the currently trading cryptocurrencies to be worth that much more! This so-called "ban" is actually making all current cryptos an even better more rare investment and should lead to new all time highs soon!
This is a great time to reload and add more cryptos to your ports! But don't wait long as China and all their rich bankster friends around the world are just licking their chops and waiting to pounce on this dip.
