I had bought various cryptocurrencies during 2017 and held them all throughout the year without any sales. I sold them only in 2018 with losses. 

1. Should I declare them while i file my taxes for 2017 mentioning how much I bought?

2. If not, should I be declaring them in the next year tax returns mentioning the losses?

1) No, you do not need to record the purchases of your cryptocurrencies that you bought and did not sell.

2) You will need to report the sales of the cryptocurrencies during 2018 on your 2018 tax return as a sale of an investment (capital gains and losses).
