30% BTC (most stable) 20% LTC (first adaptation)
10% Neo & 10% ICX (Asia's most promising block chains), last 30% even with ADA, NEM, IOTA and STEEM (biggest risk to return). This would be a safe mix with great promise of return. If you want greater returns - TRX, XVG, SIA and RDD, however these require greater management as they are prone to drop as fast as they rise.
