Can you please give me a list of your altcoins you invested with or hodl? What are those wallets you are using to hold your altcoins? I already have 25 TENX PAY and 2.5 QTUM. Having an awesome team members really is a big factor.
I hold bitcoin, litecoin and etherium for long term because i see the possibility that this coins will have a great result in near future.
if you are looking for an existing coins stratis, eth are both good together with waves,neo and nem but if you are also looking for ico coin you can try what i have inside my signature campaign as they got already an existing business and funding them will help them to achieved more so both will benefits.
