What do you think ?

It is pretty much impossible to guess future profits. You may calculate using past experiences and just say "ok iota will make me rich in 2 years". But noone knows if its not going to be hacked next day. In cryptocurrencies, everything is possible, never forget it.
By the way my favourite coins are IOTA and Monero for future.

Certainly among your proposals C is the best choice but if I can give my advice:

1) wait another two weeks until the btc fork when it's worth over $ 7,000 and the alts are much lower now .... so you'll always have your 3 btc but you'll be able to buy a lot more coins and you'll also have money free from bitcoin s2x (you can resell or hold)

2) Do not buy only 3-4 coins but divide your investment into at least 10 coins

3) if you can keep your investment for at least 2-3 years (5 years in crypto does not exist :-) then i will advise you:

iota-omg-elixir (you already know) but still
Neo - Qtum - Shift - Sys - Kore - Eidoo - Xby - Stratis - Radium - Nav - Xspec

Good luck and do your research

Investment decision require serious homework before gonna do deposit that amount. If you have proven track record in trading you can choose good altcoins while prices are digging around low levels. Neo and qtum have good potential if teams behind projects can keep their promises on whitepaper without doing stupid things.

There will be no fork.  Everyone was stacking up BTC-s to get free coins out of thin air due to the fork, but thats not gonna happen.  Now people will sell some of their BTC, and invest more on alts again.

If you listen to me, you will buy some alts now, before their price compared to BTC rise again.
