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.
I don't think someone will be ready for daytrading if they only do a long-term trading. I mean, he may know the basic trading but will still need lot of experience and knowledge to be able to make profit in daytrading as everything is very confusing and time consuming.
