$1000? I think my long term portfolio would be graphene biased and would look like:
6000 Bitshares at about 5c each = $300 [I think this is cheap for a share in a Decentralised Exchange]
200 Steem at $1 each = $200 [I like the plateform and I use it]
3 LTC at $55 each = $165 [Because it follows the BTC price and I can use it for transactions and convert to other coins easily]
120 EOS at 0.6c each = $120 [Just in case]
and I would split the remaining $215 for short/medium term investment in other altcoins and maybe keep some BitUSD as a cash reserve ready for a good opportunity to buy cheap coins.
PS: This is not financial advice, just a random opinion.
