If coinbase giving you bitcoin for low fee and competitive price then go for it.I suggest if you can,then buy bitcoins using localbitcoins as you can probably find a good bitcoin price there and also you can negotiate with sellers which you can't do on coinbase and similar websites.Good time to buy bitcoin is always 'now'.I would suggest everyone,don't keep ignoring 'buying bitcoin' thinking that price is too high because later you will regret that you missed the chance to buy bitcoin in past at low price.So buy now and hodl long term and eventually you will profit
