Bitfinex only have Wire transfer for deposits and the same thing applies to Kraken unless you are from Europe then you could use SEPA. What I can suggest is to create a PayPal or Skrill account and trade with invididuals, It should cost you less when It comes to the fees and If you really want to use the exchanges you mentioned afterwards you could deposit USDT (Tether) instead.
where can i find the individuals to trade with? are there any marketplaces for this?
and how I can be sure that I'll get the coins after I make the payment in skrill or paypal?
If you will use Paxful as suggested above, the funds will be hold by an escrow automatically. It's you who people should trust because you will be the one using the reversible payment method. You must also know that you could be asked for your ID, passport by users because sometimes they don't trust with whom they trade. I suggest checking Paybis.com too, the fees are not that competitive though.
