just close your eyes and buy.
I bought at 1,100sats, 900sats and now buying more at 550sats.
every time the price goes down is an opportunity to buy and im not being sarcastic either.
You have a good strategy. Dollar-cost averaging is your friend.
http://www.investopedia.com/terms/d/dollarcostaveraging.aspbuy when prices go down
sell when prices go up
buy in pieces to average down ur invest per coin
sell in pieces to not sell all to early when it keeps raising higher
just some hints if u in this for trading
a trader who buy on rise is doing wrong
same for a trader who sell as falling prices
in case u in NEM for the long run which i strong suggest
its easyer
buy buy buy each month buy what u can afford
afters years of accumulation if things go well
decades of payouts will follow even if u just sell the earned fees and not touch ur base share of total coins
