Having accumulated bitcoin once it dropped under $3000 from late november until early March, I've now switched over to diversifying out with an altcoin spread. I picked up 15 altcoins last week, will continue buying for the next couple months probably.
I might add a few coins, but what do you think of my altcoin spread. Note that I already own a lot of BTC, a good amount of ETH, and a little BCH and LTC and DOGE. I don't plan on buying more of those coins.

BTT can fit harmoniously into your list. Bittorrent, the coin of the same name of the torrent client which belongs to the Creator of TRX.
