Here I think we should hold atleast 5 btc for the future and altclins with the value of 5 btc .
I mean 1btc= eth
1btc = dash
1btc = ripple
1btc = Monero
1btc = dgb .
With the good future of the Bitcoin these altcoins also has bright future , so here in my opinion we should have these altxoins , it may be possible with the time increase they are also have the increase in value and demand and will reach to the value of the Bitcoin , so here we are not only making money with the Bitcoin but also with the other altcoins and turning our risk into minimum by holding many altcoins with Bitcoin .
This is a good idea. You diversified our 1 bitcoin to other top coins being traded. For what we know, this coin has great potential to grow more. I think its time to start accumulating. Oh BTW this is not the only retirement plan I have. This is only to augment, since bitcoin is very promising.
ETH have smart contract is very good and recently, it very help more ICOs success as BAT, SC, ...
