This is the easest thing in crypro world, casually buy the top ten market value, even if the loss is just a little bit. Go ahead，my friend.
Yes even if there is loss initially, it will be replaced by profit in long term after the consistent rise in the value. I have been a lover of Bitcoin and ETH and few other altcoin like LTC etc.
They are actually for profit in long term. Unfortunately due to the high price, many investors refrains to invest and go for the coins with low value which are at times not so advanced and hence cost them money. Despite a portion of Bitcoin or few ETH might do the job may what come.
