I think better become long term holding if you have good financial income, but if trading is main your income trader is good ideas and you don't have many alternative way to earn much profit. Become holder need good financial condition and difficult without get income every day or every month become long term holder, some trader make trading as their main job and need to earn profit every day by making short term trading than holding.
If you to be long term holder or investor make your financial is good firstly before not scare when hold bitcoin and altcoin assets for long term.
