If the price doesn't reach $1300, then bitcoin failed or something seriously went wrong. You will save yourself a lot of time and money.
Disadvantages: You miss the gains from 350 to 1300
Great advice! For a troll... Do you seriously expect even the worst newbie noob to believe in your meaningless nonsense?
I dunno, it's not a strategy I'm going to follow, but it doesn't seem like an unreasonable strategy - not much difference to buying when price rises above the upper Bollinger Band. It also frees up funds to invest in other things while we wait for a clear movement from BTC.
Buying now has more risks than buying later in an confirmed uptrend; which is what the OP is all about.
as usual: more risk, more (possible) reward ;-)
