As you are new u should go for long term trading in my opinion as it is much safer route but invest in good coin only. After you become comfortable then go for short trading as it requires patience ,time and decisive approach.
Right, for all new traders it is good to trade for long term because Im long term trader and I know how reliable it is for me. In trading, when you are new you can not make sudden good decision but you will have to make right decision that's why Better make long term trading and you will not get frustrated by market change as well.
