I see from the current market conditions, all famous coins are green ,not wrong buy now just to keep, if up there is a higher increase I suggest investation half your capital to buy coins from the 1 to 5 coinmarcetcap rating if you want to make a profit
Always bare in mind to buy during low price in the market, and sell at high because that's the best opportunity for us to grab on this point. When you're interested to buy at this moment, that's for sure you'll be able to hold a cheaper coin price then wait for the right time for it's price to increase. By the moment it's price increases at profitable value, you can decide selling your holdings and take the profit as your ROI.
