The thing we must understand that investment is always at risk including cryptocurrencies, moreover we know that cryptocurrencies are investments like roller coasters so that do not ever invest with money in large sizes, better relaxed and investing only money we usually consider lost.
this is true, I think by investing using the money that we could consider not needed, etc we gonna make better decision than using some borrowed money mainly because we aren't within some pressure which mean we could make decision wisely, I think it's the basic of investing that everyone should know and understand since it could save us from losing.
using loan for buying cryptocurrency was high risk,except we have regular salary that coule cover its payment in every month and fill our needs. Some investor take this high risk strategy due they have monthly salary or business which its income used to other part.but not all altcoin should buy ,we must take only major coins.
