every time there is a dip, its always an opportunity to buy, because the the price will obviously be low which in turn will result in profit when there is prize hike. the best coin to be on the dip is the EOS which has more potential to moon,looking at the market.
Definitely, while the market has been dropped, keep to invest more and be patient by holding it, because it is worthy. When the market will arise, the value of all tokens is feasible to pump up immensely and the token you've been hold has a chance to purchase it and gain good profits. I think all tokens has a great potential in crypto world, just be wise to choose on which tokens are great to invest.
