What i think:
Don't buy index funds, do your own research invest in coins you do your research and do your own index fund! And if you buy those index funds where are you going to store them? can they be stored in a wallet like a ledger?
I'm going to stick with my plant, buy what i believe in, which right now is VEN, EOS and NEO ( i like cryptos that give me dividends and that have good companies behind them)
The market moving forward is either going to go up, down or sideways :P JK, i think we will se a stable 9k-11k btc price until may at least and only then will the price increase smashing trough 20k and going right to 40-50k, but this is just speculation which i hate to give
