The best thing is to buy Ethereum, Bitcoin and such coins as:
1. TRX
2. Ripple
3. Litecoin
4. NEO
But the last four it's my opinion - you can choose something more
However, put most of your instment into Ethereum and Bitcoin
It's for save
Ripple is not decentralized, so it might not be a good choice.
all these coins have a huge market cap and you can't make money with 1200$ on them you should try to find the next trx,neo.... these coins are mostly store of value than investment.
