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.
you want to buy alt coin and hold it long. I suggest you buy eth or waves for holding. today this coin price is low and I think this coin price can be increase. you can keep this coin her own wallet. I think this wallet is safety.
