I am afraid I did not understand you well. You meant you are looking for a safe altcoin wallet? If so, which altcoin particularly?

Please tell Altcoin wallet

For the most popular altcoins such as DASH, ETH, ZEC, ETC, DOGE, REP etc. I recommend JAXX wallet. For the smaller ones you should download desktop wallet for any specific altcoin. However for the desktop wallets you should need enough free space on your device to store all the block data during the obligatory synchronization.

Thank you so much for good answer!

I know but sync. Process very slow. It will take much more hours for this process.

This is how these wallets work, but there is no risk for your funds. Anyway there are online wallets as well but I am a little bit suspicious on their security.

Yes I know I also agree with you

Jaxx wallet not for altcoin

Why do you think so? JAXX is an integrated wallet that store more than 10 altcoins and tokens with built-in exchange function through shapehift.io. I am using it and it works pretty well for me.
