Buy coins from exchange and withdraw them outside of the exchange.
Also some bitcoins are handy to keep in the exchange in case zhalox decides to dump some more Moneros.
Forget the coins for few years and let's see what is the market in 2018-2020... I think it is higher than today (or Monero has died).
Who is this zhalox ? Is he this person : https://bitcointalksearch.org/user/zhalox-9380 ?
Why would he want to hurt Monero ? He seems to like XMR.
He is most likely a supporter of XMR but he has way too weak and shaky hands. It is better to buy his coins now than later when the price is higher.
Monero needs super-strong hands who are not dumping coins, in my opinion.
By the way, dumping a coin is the stupidest thing to do IMO. Argument is simple: if you dump 10 000 coins, you get, let's say 29 btc. On the other hand, if you put 500 coins sell walls 20 times slowly slowly (like you feed a baby) to the markets, you will get - let's say 30.5 BTC. So this case you lose 1.5 btc and that's the cost of dumping. If you feel like selling, don't dump but put some sell orders to the markets instead. You get more money and you are not destroying nice charts.
