My top 3 altcoin picks for 2018 are:

1. Speedcash SCS - tiny supply below 500k, burst and vault techno, decentralized banner network, anonymous messenger etc. - my favs choice

2. ECC coin due to low price 10-11 sats and a vision to compete with SIA in file storage territory

3. CargoX, due to transferring global supply chain services on top of blockchain
