If you want keep your bitcoin safe then i will recommend you to use blockchain wallet for storing and please enable security settings like 2FA code,block tor request ,email verification etc.It will make your wallet more secure.
           thank you.

bitcoin can be used in regular transaction but the biggest problem is acceptance of bitcoin in localities because most of the people(like plumbers,barber etc) don't have knowledge about bitcoin or have a less knowledge. The greatest idea which i have discovered that at first tell them about  bitcoin and then just tell them growth of bitcoin in near future . If you are telling to a cafe owner  just tell to him that price of a coffee is just 3 - 4$ and it will remain 3-4 $ every time, the value of 3 - 4 $ will not increase but if they accept bitcoin (like 3 $ =  0.00118 BTC ) then there will be a chance to to get more (if bitcoin price increases). we know it very clearly that bitcoin's future is very much bright in near future .. so i have applied this in localities people  . I think it will also help you to understand them.
          
      thank you.

there are many altcoins in the world . I think some of them have a great future like bitcoin but most altcoins don't have a future . If you want to invest on
altcoins then i will suggest you to invest on ETH , LTC etc. now a days most of the altcoins are used only for  trading .

my favorite cryptocurrency is Bitcoin and ETH but all time favorite is bitcoin .

As I use blockchain wallet as for their security and services..I will recommend you to use blockchain wallet because it is the world's  first bitcoin wallet and very very trusted than others .
          Thank you.

I think no late to buy bitcoin . If you are thinking  bitcoin  as an asset then you will be profitable as  in near future bitcoin is price will reach approx 10000 USD (according to  news.bitcoin.com) and if you are thinking bitcoin as an global currency then also you will gain profit because you can use bitcoin anywhere in the world easily and securely.

The coins you have named all are good for invest .. If you take BTC then in near future it will reach approx 10000 usd(according to news.bitcoin.com) . If you take ETC it's future is also good  and LTC , dash all are good and have a good future . I will suggest you to invest on BTC,LTC,ETC,DASH coins. I am sure that if you invest on those coins you will always gain profit. thank you

According to me, bitcoin is not only an asset . Firstly we know bitcoin as a global currency . As it's popularity is growing up day by day so value of bitcoin is increasing  so many people is thinking bitcoin as an asset . Bitcoin is a decentralized global currency which should be treated as a currency instead of an asset.
