Strategy: Sell at high prices, buy on cheap.
That's the best strategy

Can you also tell me how to decide, when prices are high or low. Taht would be great. Im hodling atleast one year to avoid taxation. And the top #10 on coinmarketcap are a good start for long term hodling IMO. Additionally, some promising small caps, which might make a run in the next 12 month and that's it.
