My strategy:
» I look for coins that have 30+ developers.
» The price should be at the bottom relative to the weekly chart.
» Trading volumes should be increasing.
Then I buy this coin.
When the coin makes x2, I sell half, withdrawing my invested funds, and I don't care about its further fate.
Then, for every x10, I take 50% profit until my capital reaches 1/10 of a bitcoin, at which point I will cash out everything.
Of course, the coin may not increase in price and then will remain a dead weight, but I will not sell, as the market is unpredictable; anything can happen.
I try to stick to the strategy: "Do not close at a loss".
Wishing everyone successful trading.
