I have invested in this. There is a strategy that could be used to get the initial investment back quicker. Say for example you invest $100, if the payouts average 1% or approx $1 a day you could convert interest daily or weekly to DAV coin then instead of transferring out Bitcoin transfer out DAV to Coinexchange.io

If DavorCoin is around for 3 months or beyond you should recoup the initial investment and then afterwards you will be playing with house money

The reason I invested was I am planning on buying altcoins weekly with some\all of the interest so if things do go pear shaped then hopefully the altcoins value will rise in due course and make up for it. If DavorCoin is around for 90-100 days from my initial lend I will turn a profit

There is one other point of interest - When BitConnect crashed the BitConnect coin slumped to approx $25 so if DavorCoin reaches a similar standing even if the platform crashed you may end up recouping a proportion of your initial investment so that may bring down the amount of days further
