Just wait good news from bitcoin and with no doubt i believe bitcoin price will rise again, but may be not sooner. Patience is key to wait that, buy now or wait may be it will little down then hold we'll get much profit if bitcoin price rise high like in 2017.
I agree on being patiently waiting. Though, There's also a limitation to it. Quoting this statement "get much profit "IF" it rise like 2017", Like I said there's a limit. For example, patiently waiting for rates like 2017, please expect the worst (Optimistic is good but be more realistic). At this rate it's impossible for Bitcoin to reach that rates again.
It's more realistic to play smart, There's no problem in Holding but be more strategic. Maximize the possibilities of earning, set a percentage of ROI on when to sell and Set a buying rate before buying so that your money is not sleeping hence it's movng.
