Here is the deal - buy $3000 worth of Ethereum and $1000 of some coin like LTC or Wave or GNT. Diversify and possibly you’ll get a better outcome at the end. But hold them long term - it seems to be the best practice nowadays.
If you are considering gambling than some “shitcoins” are your best friends )) But be aware that you may lose it all.
In any case be ready to lose it all, who knows what can happen while gambling, that is why never invest more than 30% of all your assets.
I invested a year ago and sold only small amount to my friend, the rest is always on hold. It’s proved to be the best tactics so far.
