My advice to accumulate bitcoin as a newbie would be to spend time researching and participating in forums etc and you will accumulate satoshis at the same time that you accumulate experience and knowledge. If you spend time learning you'll earn bitcoin one way or the other.
Thats also another options learn well and get your rank high and join signature. Theres no other way to get bitcoin without investment here aside from signature or join some raffle or free giveaway bitcoin here. But OPs talking about probably the investment part since he is asking if his gonna wait to go down. So my response is about dca instead.
