I would wait some days till monero s LL and start getting up again. I would put most of the money in monero, it has big volume, great community, top support and many updates will follow.
Also investing some amount in BTC won't be a bad idea. LTC and ETH for short-mid time investments will also be a good idea. But keep in mind that most TOP altcoins, besides monero, are ATH, so they may go down soon. ...i would wait some days/weeks for altcoins.
